LM837 www.ti.com SNOSBZ6C – MAY 1999 – REVISED MARCH 2013 LM837 Low Noise Quad Operational Amplifier Check for Samples: LM837 FEATURES 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. 1 2 • • • • • • 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 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. Schematic and Connection Diagrams Figure 1.

See http://www.ti.com for other methods of soldering surface mount devices. (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not ensure specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not specified for parameters where no limit is given, however, the typical value is a good indication of device performance. If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. Unless otherwise specified the absolute maximum input voltage is equal to the power supply voltage. For operation at ambient temperatures above 25°C, the device must be derated based on a 150°C maximum junction temperature and a thermal resistance, junction to ambient, as follows: LM837N, 90°C/W; LM837M, 150°C/W.
