LM837

Low Noise Quad Operational Amplifier

General Description

The LM837 is a quad operational amplifier designed for low

noise, high speed and wide bandwidth performance. It has a

new type of output stage which can drive a 600

Ω load, mak-

ing it ideal for almost all digital audio, graphic equalizer,

preamplifiers, and professional audio applications. Its high

performance characteristics also make it suitable for instru-

mentation applications where low noise is the key consider-

ation.

The LM837 is internally compensated for unity gain opera-

tion. It is pin compatible with most other standard quad op

amps and can therefore be used to upgrade existing sys-

tems with little or no change.
