LM380 power audio amplifier circuit

This LM380 electronic schematic circuit presented in this page is audio power amplifier designed for consumer applications.

LM3876 56W audio amplifier circuit

Audio power amplifier presented in this electronic schematic circuit is based on the LM3876 audio amplifier IC which is capable of delivering 56W of continuous average power to an 8 ohms load impedance with low distortion ( 0.1% THD+N from 20Hz–20kHz) .
To build an audio power amplifier based on the LM3876 we need just few external components.
For the LM3876 audio power amplifier we need to use a 35 volts dual power supply .
