Dual Low Offset
Operational Amplifier
LM358A LM358B
Dual Low Offset Operational Amplifier
General Description
•
The LM358A/B series consist of two independent, high gain
and internally frequency compensated operational amplifiers.
They can 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.
•
The LM358A/B is available in SOP-8 and DIP-8 packages.
SOP-8
DIP-8
Features
