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
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.

Notes:
6. Limits over the full temperature are guaranteed by design, but not tested in production.
7. The input common-mode voltage of either input signal voltage should not be allowed to go negatively by more than 0.3V (at +25oC). The upper end of the
common-mode voltage range is VCC-1.5V (at +25oC), but either or both inputs can go to +36V without damages, independent of the magnitude of the
VCC。
