Usually an power amplifier circuit based TDA2030 designed to provide output power about 20 Watts. But the amplifier circuit design shown here is designed to provide power 8 Watt.
The design of the power amplifier circuit is shown here has the advantage that the quality of sound produced almost no distortion at all. TDA2030 amplifier has an input sensitivity of 200mV.
Resistors R1 and R3 serves to adjust the amplifier gain. The power supply is used to run the amplifier circuit is +/- 15V with 2A current. Do not forget to add a heatsink on the TDA2030 IC so that heat can be channeled properly.
