LM1877

LM1877 Dual Audio Power Amplifier February 1995 LM1877 Dual Audio Power Amplifier General Description The LM1877 is a monolithic dual power amplifier designed to deliver 2W/channel continuous into 8Ω loads. The LM1877 is designed to operate with a low number of external components, and still provide flexibility for use in stereo phonographs, tape recorders and AM-FM stereo receivers, etc. Each power amplifier is biased from a common internal regulator to provide high power supply rejection, and output Q point centering. The LM1877 is internally compensated for all gains greater than 10. n n n n n Wide supply range, 6V–24V Very low cross-over distortion Low audio band noise AC short circuit protected Internal thermal shutdown Applications n n n n n n n Multi-channel audio systems Stereo phonographs Tape recorders and players AM-FM radio receivers Servo amplifiers Intercom systems Automotive products Features n 2W/channel n −65 dB ripple rejection, output referred n −65 dB channel separation, output referred Connection Diagram Dual-In-Line Package or Surface Mount Package DS007913-1 Top View Order Number LM1877M-9 or LM1877N-9 See NS Package Number M14B or N14A © 1999 National Semiconductor Corporation DS007913 www.national.com Equivalent Schematic Diagram DS007913-2 www.national.com 2 Absolute Maximum Ratings (Note 1) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and sp...
