DESCRIPTION
The TS46x is operational amplifiers able to oper-
ate with voltages as low as 1.35V and to reach a
minimum of 2Vpp of output swing when sup-
plied with 2.5V.
This device is well suited for every kind of portable
and battery-supplied equipment where low noise
and low distortion are key.
The TS461/2/4 are a cost-attractive access to the
range of the Rail to Rail Op-Amps from
STMicroelectronics.

1. All voltages values, except differential voltage are with respect to network group terminal.
2. Differential voltages are non-inverting input terminal with respect to the inverting input terminal.
3. The magnitude of input and output voltages must never exceed V
CC
+0.3V.
4. Short-circuits can cause excessive heating and destructive dissipation.
