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 >600 Low input noise voltage 4.5 nV/ Low total harmonic distortion 0.0015% Low offset voltage 0.3 mV 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 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.

Also Recommended LM4562 Dual, High Fidelity, Low Noise LME49740 Much Lower Distortion (0.00003%), Better Specs All Around

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
