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 CC + and V CC - .

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 :
I source = 65mA - I sink = 75mA

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 CC + +0.3V.
