LM358 LINEAR INTEGRATED CIRCUIT

DUAL OPERATIONAL AMPLIFIER

DESCRIPTION

The Contek LM358 consists of two independent high gain,
internally frequency compensated operational amplifier. It can
be operated from a single power supply and also split power
supplies.

FEATURES

*Internally frequency compensated for unity gain.
*Wide power supply range 3V - 32V.
*Input common-mode voltage range include ground.
*Large DC voltage gain.

SOP-8

APPLICATIONS

*General purpose amplifier.
*Transducer amplifier.
