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 ponents, and still provide flexibility for use in stereo phonographs, tape recorders and AM-FM stereo receivers, etc. Each power amplifier is biased from a mon internal regulator to provide high power supply rejection, and output Q point centering. The LM1877 is internally pensated 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
