    Very Low Offset Drift: 1mV/°C max  
    The OPA140, OPA2140, and OPA4140 op amp  
    family is a series of low-power JFET input amplifiers  
    that feature good drift and low input bias current. The  
    rail-to-rail output swing and input range that includes  
    V– allow designers to take advantage of the  
    low-noise characteristics of JFET amplifiers while  
    also interfacing to modern, single-supply, precision  
    Very Low Offset: 120mV  
    Low Input Bias Current: 10pA max  
    Very Low 1/f Noise: 250nVPP, 0.1Hz to 10Hz  
    Low Noise: 5.1nV/√Hz  
    Slew Rate: 20V/ms  
    analog-to-digital  
    converters  
    (ADCs)  
    and  
    Low Supply Current: 2.0mA max  
    Input Voltage Range Includes V– Supply  
    Single-Supply Operation: 4.5V to 36V  
    Dual-Supply Operation: ±2.25V to ±18V  
    No Phase Reversal  
    digital-to-analog converters (DACs).  
    The OPA140 achieves 11MHz unity-gain bandwidth  
    and 20V/ms slew rate while consuming only 1.8mA  
    (typ) of quiescent current. It runs on a single 4.5 to  
    36V supply or dual ±2.25V to ±18V supplies.  
    All versions are fully specified from –40°C to +125°C  
    for use in the most challenging environments. The  
    OPA140 (single) is available in the SOT23-5,  
    MSOP-8, and SO-8 packages; the OPA2140 (dual) is  
    available in both MSOP-8 and SO-8 packages; and  
    the OPA4140 (quad) is available in the SO-14 and  
    TSSOP-14 packages.

    This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with  
    appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.  
    ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more  
    susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

    (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may  
    degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond  
    those specified is not supported.  
    (2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should  
    be current limited to 10 mA or less.  
    (3) Short-circuit to VS/2 (ground in symmetrical dual-supply setups), one amplifier per package.

    APPLICATION INFORMATION  
    with total circuit noise calculated. The op amp itself  
    contributes both a voltage noise component and a  
    current noise component. The voltage noise is  
    commonly modeled as a time-varying component of  
    the offset voltage. The current noise is modeled as  
    the time-varying component of the input bias current  
    and reacts with the source resistance to create a  
    voltage component of noise. Therefore, the lowest  
    noise op amp for a given application depends on the  
    source impedance. For low source impedance,  
    current noise is negligible, and voltage noise  
    generally dominates. The OPA140, OPA2140, and  
    OPA4140 family has both low voltage noise and  
    extremely low current noise because of the FET input  
    of the op amp. As a result, the current noise  
    contribution of the OPAx140 series is negligible for  
    any practical source impedance, which makes it the  
    better choice for applications with high source  
    impedance.  
    The OPA140, OPA2140, and OPA4140 are unity-gain  
    stable, operational amplifiers with very low noise,  
    input bias current, and input offset voltage.  
    Applications with noisy or high-impedance power  
    supplies require decoupling capacitors placed close  
    to the device pins. In most cases, 0.1mF capacitors  
    are adequate. Figure 1 shows a simplified schematic  
    of the OPA140.  
    OPERATING VOLTAGE  
    The OPA140, OPA2140, and OPA4140 series of op  
    amps can be used with single or dual supplies from  
    an operating range of VS = +4.5V (±2.25V) and up to  
    VS = +36V (±18V). These devices do not require  
    symmetrical supplies; they only require a minimum  
    supply voltage of +4.5V (±2.25V). For VS less than  
    ±3.5V, the common-mode input range does not  
    include midsupply. Supply voltages higher than +40V  
    can permanently damage the device; see the  
    Absolute Maximum Ratings table. Key parameters  
    are specified over the operating temperature range,  
    TA = –40°C to +125°C. Key parameters that vary over  
    the supply voltage or temperature range are shown in  
    the Typical Characteristics section of this data sheet.  
    The equation in Figure 34 shows the calculation of  
    the total circuit noise, with these parameters:

    RS = source impedance  
    k = Boltzmann's constant = 1.38 × 10–23 J/K  
    T = temperature in degrees Kelvin (K)  
    CAPACITIVE LOAD AND STABILITY  
    The dynamic characteristics of the OPAx140 have  
    been optimized for commonly encountered gains,  
    loads, and operating conditions. The combination of  
    low closed-loop gain and high capacitive loads  
    decreases the phase margin of the amplifier and can  
    lead to gain peaking or oscillations. As a result,  
    heavier capacitive loads must be isolated from the  
    output. The simplest way to achieve this isolation is to  
    add a small resistor (ROUT equal to 50Ω, for example)  
    in series with the output.

    BASIC NOISE CALCULATIONS  
    Figure 35 illustrates both noninverting (A) and  
    inverting (B) op amp circuit configurations with gain.  
    In circuit configurations with gain, the feedback  
    network resistors also contribute noise. In general,  
    the current noise of the op amp reacts with the  
    feedback resistors to create additional noise  
    components. However, the extremely low current  
    noise of the OPAx140 means that its current noise  
    contribution can be neglected.  
    Low-noise circuit design requires careful analysis of  
    all noise sources. External noise sources can  
    dominate in many cases; consider the effect of  
    source resistance on overall op amp noise  
    performance. Total noise of the circuit is the  
    root-sum-square  
    components.  
    combination  
    of  
    all  
    noise  
    The resistive portion of the source impedance  
    produces thermal noise proportional to the square  
    root of the resistance. This function is plotted in  
    Figure 34. The source impedance is usually fixed;  
    consequently, select the op amp and the feedback  
    resistors to minimize the respective contributions to  
    the total noise.  
    The feedback resistor values can generally be  
    chosen to make these noise sources negligible. Note  
    that low impedance feedback resistors load the  
    output of the amplifier. The equations for total noise  
    are shown for both configurations.

    PHASE-REVERSAL PROTECTION  
    Although the output current is limited by internal  
    protection circuitry, accidental shorting of one or more  
    output channels of a device can result in excessive  
    heating. For instance, when an output is shorted to  
    mid-supply, the typical short-circuit current of 36mA  
    leads to an internal power dissipation of over 600mW  
    at a supply of ±18V.  
    The OPA140, OPA2140, and OPA4140 family has  
    internal phase-reversal protection. Many FET- and  
    bipolar-input op amps exhibit a phase reversal when  
    the input is driven beyond its linear common-mode  
    range. This condition is most often encountered in  
    noninverting circuits when the input is driven beyond  
    the specified common-mode voltage range, causing  
    the output to reverse into the opposite rail. The input  
    circuitry of the OPA140, OPA2140, and OPA4140  
    In the case of a dual OPA2140 in an MSOP-8  
    package (thermal resistance qJA = 180°C/W), such  
    power dissipation would lead the die temperature to  
    be 220°C above ambient temperature, when both  
    channels are shorted. This temperature increase  
    significantly decreases the operating life of the  
    device.  
    prevents  
    phase  
    reversal  
    with  
    excessive  
    common-mode voltage; instead, the output limits into  
    the appropriate rail (see Figure 22).  
    OUTPUT CURRENT LIMIT  
    In order to prevent excessive heating, the OPAx140  
    series has an internal thermal shutdown circuit, which  
    shuts down the device if the die temperature exceeds  
    approximately +180°C. Once this thermal shutdown  
    circuit activates, a built-in hysteresis of 15°C ensures  
    that the die temperature must drop to approximately  
    +165°C before the device switches on again.  
    The output current of the OPAx140 series is limited  
    by  
    internal  
    circuitry  
    to  
    +36mA/–30mA  
    (sourcing/sinking), to protect the device if the output  
    is accidentally shorted. This short-circuit current  
    depends on temperature, as shown in Figure 32.  
    POWER DISSIPATION AND THERMAL  
    PROTECTION  
    Additional consideration should be given to the  
    combination of maximum operating voltage,  
    maximum operating temperature, load, and package  
    type. Figure 36 and Figure 37 show several practical  
    considerations when evaluating the OPA2140 (dual  
    version) and the OPA4140 (quad version).  
    The OPAx140 series of op amps are capable of  
    driving 2kΩ loads with power-supply voltages of up to  
    ±18V over the specified temperature range. In a  
    single-supply configuration, where the load is  
    connected to the negative supply voltage, the  
    minimum load resistance is 2.8kΩ at a supply voltage  
    of +36V. For lower supply voltages (either  
    single-supply or symmetrical supplies), a lower load  
    resistance may be used, as long as the output current  
    does not exceed 13mA; otherwise, the device  
    short-circuit current protection circuit may activate.  
    As an example, the OPA4140 has a maximum total  
    quiescent current of 10.8mA (2.7mA/channel) over  
    temperature. The TSSOP-14 package has a typical  
    thermal resistance of 135°C/W. This parameter  
    means that because the junction temperature should  
    not exceed +150°C in order to ensure reliable  
    operation, either the supply voltage must be reduced,  
    or the ambient temperature should remain low  
    enough so that the junction temperature does not  
    exceed +150°C. This condition is illustrated in  
    Figure 36 for various package types. Moreover,  
    resistive loading of the output causes additional  
    power dissipation and thus self-heating, which also  
    must be considered when establishing the maximum  
    supply voltage or operating temperature. To this end,  
    Figure 37 shows the maximum supply voltage versus  
    temperature for a worst-case dc load resistance of  
    2kΩ.  
    Internal power dissipation increases when operating  
    at high supply voltages. Copper leadframe  
    construction used in the OPA140, OPA2140, and  
    OPA4140 series devices improves heat dissipation  
    compared to conventional materials. Printed circuit  
    board (PCB) layout can also help reduce a possible  
    increase in junction temperature. Wide copper traces  
    help dissipate the heat by acting as an additional  
    heatsink. Temperature rise can be further minimized  
    by soldering the devices directly to the PCB rather  
    than using a socket.

    It is helpful to have a good understanding of this  
    basic ESD circuitry and its relevance to an electrical  
    overstress event. See Figure 38 for an illustration of  
    the ESD circuits contained in the OPAx140 series  
    (indicated by the dashed line area). The ESD  
    protection circuitry involves several current-steering  
    diodes connected from the input and output pins and  
    routed back to the internal power-supply lines, where  
    they meet at an absorption device internal to the  
    operational amplifier. This protection circuitry is  
    intended to remain inactive during normal circuit  
    operation.

    An ESD event produces  
    a
    short duration,  
    high-voltage pulse that is transformed into a short  
    duration, high-current pulse as it discharges through  
    a semiconductor device. The ESD protection circuits  
    are designed to provide a current path around the  
    operational amplifier core to prevent it from being  
    damaged. The energy absorbed by the protection  
    circuitry is then dissipated as heat.

    When an ESD voltage develops across two or more  
    of the amplifier device pins, current flows through one  
    or more of the steering diodes. Depending on the  
    path that the current takes, the absorption device  
    may activate. The absorption device has a trigger, or  
    threshold voltage, that is above the normal operating  
    voltage of the OPAx140 but below the device  
    breakdown voltage level. Once this threshold is  
    exceeded, the absorption device quickly activates  
    and clamps the voltage across the supply rails to a  
    safe level.

    Ambient Temperature (?C)  
    When the operational amplifier connects into a circuit  
    such as the one Figure 38 shows, the ESD protection  
    components are intended to remain inactive and not  
    become involved in the application circuit operation.  
    However, circumstances may arise where an applied  
    voltage exceeds the operating voltage range of a  
    given pin. Should this condition occur, there is a risk  
    that some of the internal ESD protection circuits may  
    be biased on, and conduct current. Any such current  
    flow occurs through steering diode paths and rarely  
    involves the absorption device.

    ELECTRICAL OVERSTRESS  
    Designers often ask questions about the capability of  
    an operational amplifier to withstand electrical  
    overstress. These questions tend to focus on the  
    device inputs, but may involve the supply voltage pins  
    or even the output pin. Each of these different pin  
    functions have electrical stress limits determined by  
    the voltage breakdown characteristics of the

    Figure 38 depicts a specific example where the input  
    voltage, VIN, exceeds the positive supply voltage  
    (+VS) by 500mV or more. Much of what happens in  
    the circuit depends on the supply characteristics. If  
    +VS can sink the current, one of the upper input  
    steering diodes conducts and directs current to +VS.  
    Excessively high current levels can flow with  
    increasingly higher VIN. As a result, the datasheet  
    specifications recommend that applications limit the  
    input current to 10mA.  
    Again, it depends on the supply characteristic while at  
    0V, or at a level below the input signal amplitude. If  
    the supplies appear as high impedance, then the  
    operational amplifier supply current may be supplied  
    by the input source via the current steering diodes.  
    This state is not a normal bias condition; the amplifier  
    most likely will not operate normally. If the supplies  
    are low impedance, then the current through the  
    steering diodes can become quite high. The current  
    level depends on the ability of the input source to  
    deliver current, and any resistance in the input path.  
    If the supply is not capable of sinking the current, VIN  
    may begin sourcing current to the operational  
    amplifier, and then take over as the source of positive  
    supply voltage. The danger in this case is that the  
    voltage can rise to levels that exceed the operational  
    amplifier absolute maximum ratings.  
    If there is an uncertainty about the ability of the  
    supply to absorb this current, external zener diodes  
    may be added to the supply pins as shown in  
    Figure 38. The zener voltage must be selected such  
    that the diode does not turn on during normal  
    operation.  
    Another common question involves what happens to  
    the amplifier if an input signal is applied to the input  
    while the power supplies +VS and/or –VS are at 0V.  
    However, its zener voltage should be low enough so  
    that the zener diode conducts if the supply pin begins  
    to rise above the safe operating supply voltage level.

    IMPORTANT NOTICE  
    Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,  
    and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should  
    obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are  
    sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.  
    TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard  
    warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where  
    mandated by government requirements, testing of all parameters of each product is not necessarily performed.  
    TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and  
    applications using TI components. To minimize the risks associated with customer products and applications, customers should provide  
    adequate design and operating safeguards.  
    TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,  
    or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information  
    published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a  
    warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual  
    property of the third party, or a license from TI under the patents or other intellectual property of TI.  
    Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied  
    by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive  
    business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional  
    restrictions.  
    Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all  
    express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not  
    responsible or liable for any such statements.  
    TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably  
    be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing  
    such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and  
    acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products  
    and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be  
    provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in  
    such safety-critical applications.  
    TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are  
    specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military  
    specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at  
    the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.  
    TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are  
    designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated  
    products in automotive applications, TI will not be responsible for any failure to meet such requirements.
