LM2879 Dual 8W Audio Amplifier
General Description
The LM2879 is a monolithic dual power amplifier which of-
fers high quality performance for stereo phonographs tape
players recorders AM-FM stereo receivers etc
The LM2879 will deliver 8W channel to an 8X load The
amplifier is designed to operate with a minimum of external
components and contains an internal bias regulator to bias
each amplifier Device overload protection consists of both
internal current limit and thermal shutdown
