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.
