SPECIFICATION
DESCRIPTION
The TS902 is a RAIL TO RAIL CMOS dual opera-
tional amplifier designed to operate with a single
or dual supply voltage.
The input voltage range V
icm
includes the two sup-
ply rails V
CC
+
and V
CC
-
.
The output reaches :

This product offers a broad supply voltage operat-
ing range from 2.7V to 16V and a supply current of
only 200µA/amp. (V
CC
= 3V).
Source and sink output current capability is typi-
cally 40mA (at V
CC
= 3V), fixed by an internal limi-
tation circuit.
The TS902 can be put on STANDBY position
(only 0.5µA and high impedance outputs).
