LOW POWER DUAL OPERATIONAL AMPLIFIERS
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 sup-
ply 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, SOIC-8, TSSOP-8
and MSOP-8 packages, AS358A is available in DIP-8
and SOIC-8 packages.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods
may affect device reliability.
