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 600Ω load, making it
ideal for almost all digital audio, graphic equalizer, preamplifiers, and professional audio
applications. Its high performance characteristics also make it suitable for instrumentation
applications where low noise is the key consideration.
The LM837 is internally compensated for unity gain operation. It is pin compatible with
most other standard quad op amps and can therefore be used to upgrade existing systems with little
or no change.
