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

regulator to provide high power supply rejection, and output

Q point centering. The LM1877 is internally compensated for

all gains greater than 10.
