LM2877 Dual 4W Audio Power Amplifier

General Description

Wide supply range, 6-24V

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.

Very low cross-over distortion

Low audio band noise

AC short circuit protected

Internal thermal shutdown
