Here’s a circuit of 7W audio amplifier that is very simple and very easy to build. This amplifier is built using TBA810 as the main component with the support of a few passive components. This circuit can work well, kits and components of this circuit can be found easily at an electronics store in your area.
I’ve found some similar circuit of 7W audio amplifier circuit based TBA810, please check the following schematic diagram:
This circuit operated with general purpose power supply with output voltage about 16VDC. Use minimum 1A transformer for stereo amplifier application.
You can download the TBA810 datasheet for detailed TBA810 documentation and circuit reference:
