description

The TLC27L4 and TLC27L9 quad operational

amplifiers combine a wide range of input offset

voltage grades with low offset voltage drift, high

input impedance, extremely low power, and high

gain.

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 low-power consumption make

these cost-effective devices ideal for high-gain,

low- frequency, low-power applications. Four

offset voltage grades are available (C-suffix and

I-suffix types), ranging from the low-cost TLC27L4

(10 mV) to the high-precision TLC27L9 (900 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.
