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
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.
