AS358/358A/358B

LOW POWER DUAL OPERATIONAL AMPLIFIERS

Description

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.

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.

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.
