LOW POWER DUAL OPERATIONAL AMPLIFIERS
General Description
Features
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.

Electrical Characteristics (Continued)
Note 3: 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.
