Description
The TLC271 operational amplifier combines a wide range of input
offset voltage grades with low offset voltage drift and high input
impedance. In addition, the TLC271 offers a bias-select mode that
allows the user to select the best combination of power
dissipation and AC performance for a particular application.
Using the bias-select option, these devices can be programmed
to fit a wide range of applications. Three offset voltage grades are
available, ranging from the low-cost TLC271 (10mV) to the
TLC271B (2mV) low-offset version. The devices are offered in
both commercial and industrial operating temperature ranges.
The extremely high input impedance and low bias currents, in
conjunction with good common-mode and supply voltage rejection
make these devices an excellent choice for high performance
designs.
The devices also feature low-voltage single-supply operation with
a common-mode input voltage range which includes the negative
rail.

Applications
With the programmability options of the TLC271, a designer can
choose a very low current option allowing for extended battery life or
choose a higher current option for more performance. It is possible to
switch performance modes as the application demands change.
The TLC271 is well suited for many consumer audio, industrial and
other low power applications.
