description
The TLC27M2 and TLC27M7 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 that of general-purpose
bipolar devices.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 high slew rates make these cost-effective devices
ideal for applications which have previously been reserved for general-purpose bipolar products,but with only
a fraction of the power consumption. Four offset voltage grades are available (C-suffix and I-suffix types),
ranging from the low-cost TLC27M2 (10 mV) to the high-precision TLC27M7 (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.
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
TLC27M2 and TLC27M7. 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 TLC27M2 and TLC27M7 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).

single-supply versus split-supply test circuits
Because the TLC27M2 and TLC27M7 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
Because of the high input impedance of the TLC27M2 and TLC27M7 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.

PARAMETER MEASUREMENT INFORMATION
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.
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 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 TLC27M2 and TLC27M7 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 TLC27M2 and TLC27M7 permits the use of very large resistive values to
implement the voltage divider, thus minimizing power consumption.
The TLC27M2 and TLC27M7 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 TLC27M2 and TLC27M7 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 TLC27M2 and TLC27M7
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 0.1µV/month, including the first month of
operation.
Because of the extremely high input impedance and resulting low bias current requirements, the TLC27M2 and
TLC27M7 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).
The inputs of any unused amplifiers should be tied to ground 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 TLC27M2 and TLC27M7 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 TLC27M2 and TLC27M7 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 TLC27M2 and TLC27M7 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.

output characteristics (continued)
Although the TLC27M2 and TLC27M7 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 60Ω and 180 Ω, dependingonhowhardtheopampinputisdriven. Withverylowvalues
of R , a voltage offset from 0 V at the output occurs. Second, pullup resistor R acts as a drain load to N4 and
P
P
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 TLC27M2 and TLC27M7 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 TLC27M2 and
TLC27M7 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.
