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

† Stresses beyond those listed under “absolute maximum ratings” may
cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other
conditions beyond those indicated under “recommended operating
conditions” is not implied. Exposure to absolute-maximum-rated
conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential voltages, are
with respect to network ground.
2. Differential voltages are at IN+ with respect to IN–.
3. The output may be shorted to either supply. Temperature and/or
supply voltages must be limited to ensure
that the maximum dissipation rating is not exceeded (see
application section).
