DESCRIPTION
The TS912 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
-
.
At 3V, the output reaches :

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 limita-
tion circuit.
