AS358/358A/358B
LOW POWER DUAL OPERATIONAL AMPLIFIERS
Description
Pin Assignments
The AS358/358A/358B consists of two independent, high gain and
internally frequency compensated operational amplifiers, they are

Operation from split power supply is also possible and the low power
supply current drain is independent of the magnitude of the power
supply voltages. Typical applications include transducer amplifiers,
DC gain blocks and most conventional operational amplifier circuits.

The AS358/358A/358B series is compatible with industry standard
358. The AS358A has more stringent input offset voltage than the
AS358.
(SO-8/TSSOP-8/MSOP-8)

The AS358 is available in PDIP-8, TDIP-8, SO-8, TSSOP-8 and
MSOP-8 packages, the AS358A is available in PDIP-8 and SO-8
packages and AS358B is available in TSSOP-8 package.
