DIY audio amplifiers circuit diagram electronics projects and other related audio projects like : power amplifiers, audio systems, audio filters, vu meters, tone control, audio equalizers and more .
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 .
Electronic circuit diagram presented here is an audio power amplifier based on TDA8571J chip which is an integrated class-B output amplifier with four amplifiers in a BTL configuration, each with a gain of 34 dB.
The maximum output power delivered by TDA8571J is 40 W into a 4 ohms .
TDA8571J circuit is designed for car radio applications.
