description
NC – No internal connection
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.
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.

These devices use Texas instruments silicon-gate
LinCMOS™ technology, which provides offset
voltage stability far exceeding the stability
available with conventional metal-gate processes.
