Description

The LM358 contains two independent high gain operational amplifiers

with

internal

compensation.

The

two op

-

amps operate over a wide voltage range from a single power supply.Also use a split power supply.

Features

•

Internally frequency compensated for unity gain

•

Large DC voltage gain:100dB Wide power supply range:

•

Low input offset voltage and offset current

The device has low power supply voltage.The low powerdrain also makes the LM358agood choicefor battery

operation.

When your project calls for a traditional op-amp function,now you can streanline your design with a simple any

digital system or personal computer application,without requiring an extra 15V power supply just to have
the interface electronics you need.

The LM358 is a versatile,rugged workhorse with a thousand-and-one use,from amplifying signals from a variety

of transducers to dcgain blocks,,or any op-amp function.The attached pages offer some recipes rhat will

have your project cooking in no time.
