LM837 Low Noise Quad Operational Amplifier General Description Features 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. n High slew rate 10 V/s (typ); 8 V/s (min) n Wide gain bandwidth product 25 MHz (typ); 15 MHz (min) n Power bandwidth 200 kHz (typ) 40 mA n High output current > 600 n Excellent output drive performance n Low input noise voltage 4.5 nV/ n Low total harmonic distortion 0.0015% n Low offset voltage 0.3 mV Schematic and Connection Diagrams Dual-In-Line Package DS009047-2 Top View Order Number LM837M, LM837MX or LM837N See NS Package Number M14A or N14A DS009047-1 (c) 2000 National Semiconductor Corporation DS009047 www.national.com LM837 Low Noise Quad Operational Amplifier August 2000 LM837 Absolute Maximum Ratings (Note 1) -60C to +150C Storage Temperature Range, TSTG Soldering Information Dual-In-Line Package Soldering (10 seconds) 260C Small Outline Package Vapor Phase (60 seconds) 215C Infrared (15 seconds) 220C ESD rating to be determined.

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit is given, however, the typical value is a good indication of device performance. Note 2: Unless otherwise specified the absolute maximum input voltage is equal to the power supply voltage. www.national.com 2 (Continued) Note 3: For operation at ambient temperatures above 25C, the device must be derated based on a 150C maximum junction temperature and a thermal resistance, junction to ambient, as follows: LM837N, 90C/W; LM837M, 150C/W.
