AS358/358A/358B
LOW POWER DUAL OPERATIONAL AMPLIFIERS
Description Pin Assignments
(Top View)
The AS358/358A/358B consists of two independent, high gain and
internally frequency compensated operational amplifiers, they are
specifically designed to operate from a single power supply.
OUTPUT 1 1 8 V
CC
Operation from split power supply is also possible and the low power
INPUT 1- 2 7 OUTPUT 2
supply current drain is independent of the magnitude of the power
supply voltages. Typical applications include transducer amplifiers, INPUT 1+ 3 6 INPUT 2-
DC gain blocks and most conventional operational amplifier circuits.
GND 4 5 INPUT 2+
The AS358/358A/358B series is compatible with industry standard
(SOIC-8/TSSOP-8/MSOP-8)
358. The AS358A has more stringent input offset voltage than the
AS358.

The AS358 is available in DIP-8, TDIP-8, SOIC-8, TSSOP-8 and
MSOP-8 packages, the AS358A is available in DIP-8 and SOIC-8
