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 8Wchannel 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
