description
The TLC272 and TLC277 precision dual
operational amplifiers combine a wide range of
input offset voltage grades with low offset voltage
drift, high input impedance, low noise, and speeds
approaching those of general-purpose BiFET
devices.
The extremely high input impedance, low bias
currents, and high slew rates make these costeffective devices ideal for applications previously
reserved for BiFET and NFET products. Four
offset voltage grades are available (C-suffix and
I-suffix types), ranging from the low-cost TLC272
(10 mV) to the high-precision TLC277 (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.

The D package is available taped and reeled. Add R suffix to the device type (e.g., TLC277CDR).
In general, many features associated with bipolar technology are available on LinCMOS operational amplifiers
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 TLC272 and
TLC277. The devices also exhibit low voltage single-supply operation, 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 TLC272 and TLC277 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 handling
these devices as exposure to ESD may result in the degradation of the device parametric performance.
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.

single-supply versus split-supply test circuits
Because the TLC272 and TLC277 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
the negative rail. A comparison of single-supply versus split-supply test circuits is shown below. The use of either
circuit gives the same result.

PARAMETER MEASUREMENT INFORMATION
input bias current
Because of the high input impedance of the TLC272 and TLC277 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 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
generally measured by monitoring the distortion level of the output while increasing the frequency of a sinusoidal
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. The frequency is then increased until the maximum peak-to-peak output can no longer be maintained
(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 devices in a high-volume,
short-test-time environment. Internal capacitances are inherently higher in CMOS than in bipolar and BiFET
devices and require longer test times than their bipolar and BiFET counterparts. The problem becomes more
pronounced with reduced supply levels and lower temperatures.

APPLICATION INFORMATION
single-supply operation
While the TLC272 and TLC277 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 TLC272 and TLC277 permits the use of very large resistive values to implement
the voltage divider, thus minimizing power consumption.
The TLC272 and TLC277 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.

APPLICATION INFORMATION
input characteristics
The TLC272 and TLC277 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 VDD – 1 V at TA = 25°C and at VDD – 1.5 V at all other temperatures.
The use of the polysilicon-gate process and the careful input circuit design gives the TLC272 and TLC277 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 TLC272 and
TLC277 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 TLC272 and TLC277 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 TLC272 and TLC277 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 TLC272 and TLC277 are measured using a 20-pF load. The devices can
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 TLC272 and TLC277 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
(RP) connected from the output to the positive supply rail (see Figure 42). There are two disadvantages 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 RP, a voltage offset from 0 V at the output occurs. Second, pullup resistor RP acts as a 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 almost 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 TLC272 and TLC277 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 TLC272 and
TLC277 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.
