tda2030a amplifier circuit used in home theaters

Posted on Feb 5, 2014

This IC require less external components too, making it easier for a beginner to make this on veroboard. The original circuit I got from it`s datasheet. A little modified circuit below, This can be operated with single supply line, but that topology gives less output power, hence this bi-voltage topology is used everywhere. We need to provide +/-

12V to it. We can easily get +12V and -12V from a 12-0-12 CT step down transformer. And, as this IC doesn`t require regulated supply, we can feed voltage directly from rectifier with just a capacitor.
