The LM837M/NOPB is a low noise 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 600R load, making it ideal. 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.
