The TD7379 powerful Classd AB Audio amplifier processor which works in either dual mode or quad ended configuration. In Bridge mode, it can able to provide up to 38 Watts at 4 ohms speaker. But in single channel mode it can deliver up to 11 watt at four ohms load. In this article I am going to discuss with TDA7379 amplifier circuit and gives the circuit diagrams.
This amplifier circuit is a perfect choice for car audio system or 4 channel audio amplifier setup. Do you want to make a 2.1 home theater system? Build a high quality 2.1 system using a single IC and reduce total cost. From the 4 channel output use the 2 channels as satellite speaker and one bridge output using as the subwoofer amplifier.

Features of TDA7379 IC
- Minimum external components needs to work.
- Stand by function inbuilt.
- No audible pop up sound from the speaker, Smooth power ON and OFF sound.
- Diagnostic facilities such as clip Indicator.
