LOW POWER DUAL OPERATIONAL AMPLIFIERS AS358/358A

General Description

The AS358/358A consist of two independent, high
gain and internally frequency compensated operational
amplifiers, they are specifically designed to operate
from a single power supply. 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 series are compatible with industry
standard 358. AS358A has more stringent input offset
voltage than AS358.

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