description
The TLC27L1 operational amplifier combines a wide range of input offset-voltage grades with low offset-voltage
drift and high input impedance. In addition, the TLC27L1 is a low-bias version of the TLC271 programmable
amplifier. These devices use the Texas Instruments silicon-gate LinCMOS technology, which provides
offset-voltage stability far exceeding the stability available with conventional metal-gate processes.
Three offset-voltage grades are available (C-suffix and I-suffix types), ranging from the low-cost TLC27L1 (10
mV) to the TLC27L1B (2 mV) low-offset version. The extremely high input impedance and low bias currents,
in conjunction 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.
In general, many features associated with bipolar technology are available in 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 all easily designed with the TLC27L1. 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.
The device inputs and output are designed to withstand – 100-mA surge currents without sustaining latch-up.
The TLC27L1 incorporates internal electrostatic-discharge (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.

single-supply versus split-supply test circuits
Because the TLC27L1 is 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.

input bias current
Due to the high input impedance of the TLC27L1 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 36). 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 is 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. When conditions other than these are
to be used, please refer to the Typical Characteristics section of this data sheet.
input offset-voltage temperature coefficient
Erroneous readings often result from attempts to measure the 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.
full-power response
Full-power response, the frequency above which the 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.
Since 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 in Figure 33. 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 37). A square wave allows 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.

While the TLC27L1 performs well using dual
power supplies (also called balanced or split
supplies), the design is optimized for
single-supply operation. This 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.

Figure 38. Inverting Amplifier With Voltage
Reference
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 consumption of the TLC27L1 permits the use of very large
resistive values to implement the voltage divider, thus minimizing power consumption.
The TLC27L1 works 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, RC decoupling may be necessary in high-frequency applications.

The TLC27L1 is 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.

input characteristics (continued)
The use of the polysilicon-gate process and the careful input circuit design gives the TLC27L1 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 TLC27L1 is
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 36 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 41).
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 TLC27L1 results 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.

Operational amplifier circuits almost always
employ feedback, and since feedback is the first
prerequisite for oscillation, a little caution is
appropriate. Most oscillation problems result from
driving capacitive loads and ignoring stray input
capacitance. A small-value capacitor connected
in parallel with the feedback resistor is an effective
remedy (see Figure 42). The value of this
capacitor is optimized empirically.
Figure 42. Compensation for Input
Capacitance
electrostatic discharge protection
The TLC27L1 incorporates an internal 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 TLC27L1 inputs
and output 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 when 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.

All operating characteristics of the TLC27L1 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
44). In many cases, adding some compensation
in the form of a series resistor in the feedback loop
alleviates the problem.

The output stage of the TLC27L1 is designed to
sink and source relatively high amounts of current

subjected to a short-circuit condition, this high

under certain conditions. Output current capability
increases with supply voltage (see Figure 43).

Figure 44. Effect of Capacitive Loads in Low-Bias Mode
Although the TLC27L1 possesses excellent high-level output voltage and current capability, methods are
available for boosting this capability, if needed. The simplest method involves the use of a pullup resistor (RP)
connected from the output to the positive supply rail (see Figure 45). 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. Secondly, 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.
