DESCRIPTION
The TS912 is a RAIL TO RAIL dual CMOS opera-
tional amplifier designed to operate with single or
dual supply voltage.
The input voltage range V
icm
includes the two
supply rails V

This product offers a broad supply voltage operat-
ing range from 2.7V to 16V, a supply current of only
400
A/amp (V
CC
= 10V) and a high output current
capability fixed by an internal limitation circuit :

Notes :
1. All voltage values, except differential voltage are with respect to network ground terminal.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
3. The magnitude of input and output voltages must never exceed V
