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.

These devices use Texas Instruments silicon-
gate LinCMOS

 technology, which provides

offset voltage stability far exceeding the stability
available with conventional metal-gate pro-
cesses.

The extremely high input impedance, low bias
currents, and high slew rates make these cost-
effective 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.
