There is a tutotial to make a 40 Watt Audio Amplifier at home by using single IC, TDA7388. A simple audio amplifier circuit can be made at home.

4×40 Watt Quad Audio Amplifier using TDA7388 at home with amazing sound quality. The TDA7388 is used inside good stereo systems. I have used this IC to make a home theater system of 160W approximately. This home made amplifier drives 4 speakers separately as it provides 4-Channel output. To achieve a good quality of output you need a good power supply and a proper heat sink for IC because in action, TDA7388 IC is dispensing a lot of heat.

It is the basic test circuit.The very best feature of this IC is that it doesn’t need so many external components, as no external components are supplied in circuit except small capacitors, which are basically used for filtering input.

To add more customization to this circuit, you can also add a bass-treble circuit or any other external equalizer to your amplifier. I used two different bass-treble circuits for my amplifier.

a closer look to our Amp…. Don’t forgot to put a solid heat sink with the IC
