Input Range Includes the Negative Supply  
Input Range Operates to Positive Supply  
Rail-to-Rail Output  
are family of 36V, single-supply, low-noise  
a
operational amplifiers with the ability to operate on  
supplies ranging from +2.7V (±1.35V) to +36V  
(±18V).  
These  
devices  
are  
available  
in  
micro-packages and offer low offset, drift, and  
bandwidth with low quiescent current. The single,  
dual, and quad versions all have identical  
specifications for maximum design flexibility.  
Gain Bandwidth: 3MHz  
Unlike most op amps, which are specified at only one  
supply voltage, the OPAx171 family is specified from  
+2.7V to +36V. Input signals beyond the supply rails  
do not cause phase reversal. The OPAx171 family is  
stable with capacitive loads up to 300pF. The input  
can operate 100mV below the negative rail and within  
2V of the top rail during normal operation. Note that  
these devices can operate with full rail-to-rail input  
100mV beyond the top rail, but with reduced  
performance within 2V of the top rail.  
Low Quiescent Current: 475µA per Amplifier  
High Common-Mode Rejection: 120dB (typ)  
Low Input Bias Current: 8pA  
Industry-Standard Packages:  
8-Pin SOIC  
8-Pin MSOP  
14-Pin TSSOP  
microPackages:  
Single in SOT553  
Dual in VSSOP-8  
The OPAx171 series of op amps are specified  
from 40°C to +125°C.

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.

SBOS516C SEPTEMBER 2010REVISED JUNE 2011  
APPLICATION INFORMATION  
The OPAx171 family of operational amplifiers provide  
high overall performance, making them ideal for many  
general-purpose applications. The excellent offset  
drift of only 2µV/°C provides excellent stability over  
the entire temperature range. In addition, the device  
offers very good overall performance with high  
CMRR, PSRR, and AOL. As with all amplifiers,  
applications with noisy or high-impedance power  
supplies require decoupling capacitors close to the  
device pins. In most cases, 0.1µF capacitors are  
adequate.  
This device can operate with full rail-to-rail input  
100mV beyond the top rail, but with reduced  
performance within 2V of the top rail. The typical  
performance in this range is summarized in Table 2.  
PHASE-REVERSAL PROTECTION  
The OPAx171 family has an internal phase-reversal  
protection. Many 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 of the OPAx171 prevents phase  
reversal with excessive common-mode voltage.  
Instead, the output limits into the appropriate rail. This  
performance is shown in Figure 37.  
OPERATING CHARACTERISTICS  
The OPAx171 family of amplifiers is specified for  
operation from 2.7V to 36V (±1.35V to ±18V). Many  
of the specifications apply from 40°C to +125°C.  
Parameters that can exhibit significant variance with  
regard to operating voltage or temperature are  
presented in the Typical Characteristics.

GENERAL LAYOUT GUIDELINES  
-18V  
37VPP  
For best operational performance of the device, good  
printed circuit board (PCB) layout practices are  
recommended. Low-loss, 0.1µF bypass capacitors  
should be connected between each supply pin and  
ground, placed as close to the device as possible. A  
single bypass capacitor from V+ to ground is  
applicable to single-supply applications.

CAPACITIVE LOAD AND STABILITY  
or even the output pin. Each of these different pin  
functions have electrical stress limits determined by  
the voltage breakdown characteristics of the  
particular semiconductor fabrication process and  
specific circuits connected to the pin. Additionally,  
internal electrostatic discharge (ESD) protection is  
built into these circuits to protect them from  
accidental ESD events both before and during  
product assembly.  
The dynamic characteristics of the OPAx171 have  
been optimized for commonly encountered 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 (for  
example, ROUT equal to 50Ω) in series with the  
output. Figure 38 and Figure 39 illustrate graphs of  
small-signal overshoot versus capacitive load for  
several values of ROUT. Also, refer to Applications  
Bulletin AB-028 (SBOA015), available for download  
from the TI website for details of analysis techniques  
and application circuits.  
These ESD protection diodes also provide in-circuit,  
input overdrive protection, as long as the current is  
limited to 10mA as stated in the Absolute Maximum  
Ratings. Figure 40 shows how a series input resistor  
may be added to the driven input to limit the input  
current. The added resistor contributes thermal noise  
at the amplifier input and its value should be kept to a  
minimum in noise-sensitive applications.

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 the operational amplifier connects into a circuit,  
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 ESD cells and rarely involves the absorption  
device.

Capacitive Load (pF)  
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. The zener voltage  
must be selected such that the diode does not turn  
on during normal operation.  
Figure 39. Small-Signal Overshoot versus  
Capacitive Load (100mV Output Step)  
ELECTRICAL OVERSTRESS  
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.  
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

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.
