description
NC 鈥?No internal connection
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鈩?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
碌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.
