description
The TLC274 and TLC279 quad 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 BiFET
devices.
These devices use Texas Instruments
silicon-gate LinCMOS
TM
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 BiFET and
NFET products. Four offset voltage grades are
available (C-suffix and I-suffix types), ranging
from the low-cost TLC274 (10 mV) to the high-
precision TLC279 (900
V). 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.

description (continued)
In general, many features associated with bipolar technology are available on LinCMOS
TM
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
TLC274 and TLC279. 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 TLC274 and TLC279 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.

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 the noninverting input with respect to the inverting input.
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).
