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 compo-
nents, and still provide flexibility for use in stereo phono-
graphs, tape recorders and AM-FM stereo receivers, etc.
Each power amplifier is biased from a common internal regu-
lator to provide high power supply rejection, and output Q
point centering. The LM1877 is internally compensated for
all gains greater than 10.
