LM1877 Sound Amp

Sound amp used on many arcade games, most notably Pacman, Mspac, JrPac.

General Description
The LM1877 is a monolithic dual power amplifier designed
to deliver 2W/channel continuous into 8X loads. The
LM1877 is designed to operate with a low number of external
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 LM1877 is internally compensated
for all gains greater than 10.
