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.
