LM2877 Dual 4W Audio Power Amplifier
General Description
The LM2877isa monolithic dual power amplifier designed deliver 4W/channel continuous into 8X loads. The
LM2877is designedto operatewithalow numberof exter-
nal components,andstill provide flexibilityforusein stereo
phonographs, tape recordersand AM-FM stereo receivers,
etc. Each power amplifieris biased froma common internal
regulatorto provide high power supply rejectionand output point centering. The LM2877is internally compensated
forall gains greater than10,and comesinan 11-leadsin-
gle-in-line package.
Features 4W/channel b68dB ripple rejection, output referred b70dB channel separation, output referred Wide supply range, 6-24V Verylow cross-over distortion Low audio band noiseAC short circuit protected Internal thermal shutdown
Applications Multi-channel audio systems Stereo phonographs Tape recorders and players AM-FM radio receivers Servo amplifiers Intercom systems Automotive products
