description (continued)

These devices use Texas Instruments silicon-gate LinCMOS technology, which provides offset voltage

stability far exceeding the stability available with conventional metal-gate processes.

The extremely high input impedance, low bias currents, and low power consumption make these cost-effective

devices ideal for high gain, low frequency, low power applications. Four offset voltage grades are available

(C-suffix and I-suffix types), ranging from the low-cost TLC27L2 (10 mV) to the high-precision TLC27L7

(500 µV). These advantages, in combination with good common-mode rejection and supply voltage rejection,

make these devices a good choice for new state-of-the-art designs as well as for upgrading existing designs.

Ingeneral, manyfeaturesassociatedwithbipolartechnologyareavailableinLinCMOS operationalamplifiers,

without the power penalties of bipolar technology. General applications such as transducer interfacing, analog

calculations, amplifier blocks, active filters, and signal buffering are easily designed with the TLC27L2 and

TLC27L7. The devices also exhibit low voltage single-supply operation and ultra-low power consumption,

making them ideally suited for remote and inaccessible battery-powered applications. The common-mode input

voltage range includes the negative rail.

A wide range of packaging options is available, including small-outline and chip-carrier versions for high-density

system applications.

The device inputs and outputs are designed to withstand –100-mA surge currents without sustaining latch-up.

The TLC27L2 and TLC27L7 incorporate internal ESD-protection circuits that prevent functional failures at

voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.2; however, care should be exercised in

handlingthesedevicesasexposuretoESDmayresultinthedegradationofthedeviceparametricperformance.

The C-Suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized

for operation from –40°C to 85°C. The M-suffix devices are characterized for operation over the full military

temperature range of –55°C to 125°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. All voltage values, except differential voltages, are with respect to network ground.

2. Differential voltages are at IN+ with respect to IN–.

3. The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum

dissipation rating is not exceeded (see application section).

PARAMETER MEASUREMENT INFORMATION

single-supply versus split-supply test circuits

Because the TLC27L2 and TLC27L7 are optimized for single-supply operation, circuit configurations used for

the various tests often present some inconvenience since the input signal, in many cases, must be offset from

ground. This inconvenience can be avoided by testing the device with split supplies and the output load tied to

thenegativerail. Acomparisonofsingle-supplyversussplit-supplytestcircuitsisshownbelow. Theuseofeither

PARAMETER MEASUREMENT INFORMATION

input bias current

Becauseof the high input impedance of the TLC27L2 and TLC27L7 operational amplifiers, attempts to measure

the input bias current can result in erroneous readings. The bias current at normal room ambient temperature

is typically less than 1 pA, a value that is easily exceeded by leakages on the test socket. Two suggestions are

offered to avoid erroneous measurements:

1. Isolate the device from other potential leakage sources.Use a grounded shield around and between the

device inputs (see Figure 4). Leakages that would otherwise flow to the inputs are shunted away.

2. Compensate for the leakage of the test socket by actually performing an input bias current test (using

a picoammeter) with no device in the test socket. The actual input bias current can then be calculated

by subtracting the open-socket leakage readings from the readings obtained with a device in the test

socket.

One word of caution: many automatic testers as well as some bench-top operational amplifier testers use the

servo-loop technique with a resistor in series with the device input to measure the input bias current (the voltage

drop across the series resistor is measured and the bias current is calculated). This method requires that a

device be inserted into the test socket to obtain a correct reading; therefore, an open-socket reading is not

feasible using this method.

low-level output voltage

To obtain low-supply-voltage operation, some compromise was necessary in the input stage. This compromise

results in the device low-level output being dependent on both the common-mode input voltage level as well

as the differential input voltage level. When attempting to correlate low-level output readings with those quoted

in the electrical specifications, these two conditions should be observed. If conditions other than these are to

be used, please refer to Figures 14 through 19 in the Typical Characteristics of this data sheet.

input offset voltage temperature coefficient

Erroneous readings often result from attempts to measure temperature coefficient of input offset voltage. This

parameter is actually a calculation using input offset voltage measurements obtained at two different

temperatures. When one (or both) of the temperatures is below freezing, moisture can collect on both the device

and the test socket. This moisture results in leakage and contact resistance, which can cause erroneous input

offset voltage readings. The isolation techniques previously mentioned have no effect on the leakage since the

moisture also covers the isolation metal itself, thereby rendering it useless. It is suggested that these

measurements be performed at temperatures above freezing to minimize error.

PARAMETER MEASUREMENT INFORMATION

full-power response

Full-power response, the frequency above which the operational amplifier slew rate limits the output voltage

swing, is often specified two ways: full-linear response and full-peak response. The full-linear response is

generallymeasuredbymonitoringthedistortionleveloftheoutputwhileincreasingthefrequencyofasinusoidal

input signal until the maximum frequency is found above which the output contains significant distortion. The

full-peak response is defined as the maximum output frequency, without regard to distortion, above which full

peak-to-peak output swing cannot be maintained.

Because there is no industry-wide accepted value for significant distortion, the full-peak response is specified

in this data sheet and is measured using the circuit of Figure 1. The initial setup involves the use of a sinusoidal

input to determine the maximum peak-to-peak output of the device (the amplitude of the sinusoidal wave is

increased until clipping occurs). The sinusoidal wave is then replaced with a square wave of the same

amplitude. Thefrequencyisthenincreaseduntilthemaximumpeak-to-peakoutputcannolongerbemaintained

(Figure 5). A square wave is used to allow a more accurate determination of the point at which the maximum

peak-to-peak output is reached.

test time

Inadequate test time is a frequent problem, especially when testing CMOS high-volume, short-test-time

environment. Internal capacitances are inherently higher in CMOS devices and require longer test times than

their bipolar and BiFET counterparts. The problem becomes more pronounced with reduced supply levels and

lower temperatures.

While the TLC27L2 and TLC27L7 perform well using dual power supplies (also called balanced or split

supplies), the design is optimized for single-supply operation. This design includes an input common-mode

voltage range that encompasses ground as well as an output voltage range that pulls down to ground. The

supply voltage range extends down to 3 V (C-suffix types), thus allowing operation with supply levels commonly

available for TTL and HCMOS; however, for maximum dynamic range, 16-V single-supply operation is

recommended.

Many single-supply applications require that a voltage be applied to one input to establish a reference level that

is above ground. A resistive voltage divider is usually sufficient to establish this reference level (see Figure 38).

The low input bias current of the TLC27L2 and TLC27L7 permits the use of very large resistive values to

implement the voltage divider, thus minimizing power consumption.

The TLC27L2 and TLC27L7 work well in conjunction with digital logic; however, when powering both linear

devices and digital logic from the same power supply, the following precautions are recommended:

1. Power the linear devices from separate bypassed supply lines (see Figure 39); otherwise, the linear

device supply rails can fluctuate due to voltage drops caused by high switching currents in the digital

logic.

2. Use proper bypass techniques to reduce the probability of noise-induced errors. Single capacitive

decoupling is often adequate; however, high-frequency applications may require RC decoupling.

input characteristics

The TLC27L2 and TLC27L7 are specified with a minimum and a maximum input voltage that, if exceeded at

either input, could cause the device to malfunction. Exceeding this specified range is a common problem,

especially in single-supply operation. Note that the lower range limit includes the negative rail, while the upper

range limit is specified at V

–1 V at T = 25°C and at V

–1.5 V at all other temperatures.

The use of the polysilicon-gate process and the careful input circuit design gives the TLC27L2 and TLC27L7

very good input offset voltage drift characteristics relative to conventional metal-gate processes. Offset voltage

drift in CMOS devices is highly influenced by threshold voltage shifts caused by polarization of the phosphorus

dopant implanted in the oxide. Placing the phosphorus dopant in a conductor (such as a polysilicon gate)

alleviates the polarization problem, thus reducing threshold voltage shifts by more than an order of magnitude.

The offset voltage drift with time has been calculated to be typically 0.1 µV/month, including the first month of

operation.

Because of the extremely high input impedance and resulting low bias current requirements, the TLC27L2 and

TLC27L7 are well suited for low-level signal processing; however, leakage currents on printed circuit boards

and sockets can easily exceed bias current requirements and cause a degradation in device performance. It

is good practice to include guard rings around inputs (similar to those of Figure 4 in the Parameter Measurement

Information section). These guards should be driven from a low-impedance source at the same voltage level

as the common-mode input (see Figure 40).

Unused amplifiers should be connected as grounded unity-gain followers to avoid possible oscillation.

noise performance

The noise specifications in operational amplifier circuits are greatly dependent on the current in the first-stage

differential amplifier. The low input bias current requirements of the TLC27L2 and TLC27L7 result in a very low

noise current, which is insignificant in most applications. This feature makes the devices especially favorable

over bipolar devices when using values of circuit impedance greater than 50 kΩ, since bipolar devices exhibit

greater noise currents.

output characteristics

The output stage of the TLC27L2 and TLC27L7 is designed to sink and source relatively high amounts of current

(see typical characteristics). If the output is subjected to a short-circuit condition, this high current capability can

cause device damage under certain conditions. Output current capability increases with supply voltage.

All operating characteristics of the TLC27L2 and TLC27L7 were measured using a 20-pF load. The devices

drive higher capacitive loads; however, as output load capacitance increases, the resulting response pole

occurs at lower frequencies, thereby causing ringing, peaking, or even oscillation (see Figure 41). In many

cases, adding a small amount of resistance in series with the load capacitance alleviates the problem.

Figure 41. Effect of Capacitive Loads and Test Circuit

Although the TLC27L2 and TLC27L7 possess excellent high-level output voltage and current capability,

methods for boosting this capability are available, if needed. The simplest method involves the use of a pullup

resistor (R ) connected from the output to the positive supply rail (see Figure 42). There are two disadvantages

P

to the use of this circuit. First, the NMOS pulldown transistor N4 (see equivalent schematic) must sink a

comparatively large amount of current. In this circuit, N4 behaves like a linear resistor with an on-resistance

between approximately 60 Ω and 180 Ω, depending on how hard the operational amplifier input is driven. With

very low values of R , a voltage offset from 0 V at the output occurs. Second, pullup resistor R acts as a

P

drain load to N4 and the gain of the operational amplifier is reduced at output voltage levels where N5 is not

supplying the output current.

feedback

Operational amplifier circuits nearly always employ feedback, and since feedback is the first prerequisite for

oscillation, some caution is appropriate. Most oscillation problems result from driving capacitive loads

(discussed previously) and ignoring stray input capacitance. A small-value capacitor connected in parallel with

the feedback resistor is an effective remedy (see Figure 43). The value of this capacitor is optimized empirically.

electrostatic discharge protection

The TLC27L2 and TLC27L7 incorporate an internal electrostatic discharge (ESD) protection circuit that

prevents functional failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.2. Care

should be exercised, however, when handling these devices, as exposure to ESD may result in the degradation

of the device parametric performance. The protection circuit also causes the input bias currents to be

temperature dependent and have the characteristics of a reverse-biased diode.

latch-up

Because CMOS devices are susceptible to latch-up due to their inherent parasitic thyristors, the TLC27L2 and

TLC27L7 inputs and outputs were designed to withstand –100-mA surge currents without sustaining latch-up;

however, techniques should be used to reduce the chance of latch-up whenever possible. Internal protection

diodes should not, by design, be forward biased. Applied input and output voltage should not exceed the supply

voltage by more than 300 mV. Care should be exercised when using capacitive coupling on pulse generators.

Supply transients should be shunted by the use of decoupling capacitors (0.1 µF typical) located across the

supply rails as close to the device as possible.

The current path established if latch-up occurs is usually between the positive supply rail and ground and can

be triggered by surges on the supply lines and/or voltages on either the output or inputs that exceed the supply

voltage. Once latch-up occurs, the current flow is limited only by the impedance of the power supply and the

forward resistance of the parasitic thyristor and usually results in the destruction of the device. The chance of

latch-up occurring increases with increasing temperature and supply voltages.
