LM2877 Dual 4W Audio Power Amplifier
General Description
The LM2877 is a monolithic dual power amplifier designed
to deliver 4W channel continuous into 8X loads The
LM2877 is designed to operate with a low number of exter-
nal 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 LM2877 is internally compensated
for all gains greater than 10 and comes in an 11-lead sin-
gle-in-line package
