LM378 datasheet



The LM378 is a monolithic dual power amplifier

which offers high quality performance for stereo phonographs, tape players, recorders, and AM-FM stereo receiver, etc. The LM378 will deliver 4W channel into 8 or 16 Ohm loads. 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.
