DESCRIPTION
The TS3V912 is a RAIL TO RAIL CMOS dual
operational amplifier designed to operate with a
single 3V supply voltage.
The input voltage range V
icm
includes the two
supply rails V
CC
+
and V
CC
-
.
The output reaches :

-
+350mV

This product offers a broad supply voltage operat-
ing range from 2.7V to 16V and a supply current of
only 200
A/amp. (V
CC
= 3V).
Source and sink output current capability is typi-
cally 40mA (at V
CC
= 3V), fixed by an internal
limitation circuit.
SGS-THOMSON is offering a quad op-amp with
the same features : TS3V914.

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.
