Datasheet
 

Recommended alternative parts

  • LM4562  -  Dual, High Fidelity, Low Noise

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 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.

Features

  • High Slew Rate 10 V/μs (typ); 8 V/μs (min)
  • Wide Gain Bandwidth Product 25 MHz (typ); 15 MHz (min)
  • Power Bandwidth 200 kHz (typ)
  • High Output Current ±40 mA
  • Excellent Output Drive Performance >600Ω
  • Low Input Noise Voltage 4.5 nV/√Hz
  • Low Total Harmonic Distortion 0.0015%
  • Low Offset Voltage 0.3 mV
