This is a very simple Circuit Diagram for Amplifier of 1,2W mono audio output. The amplifier is based on a single IC TDA7052. It is in 8-pin DIL (Dual-In-Line) package. The IC TDA7052 is specially designed for battery-operated audio circuit for amplifier like tape recorders, radios etc.
The power supply for this amplifier is 3V to 18V, but we recommend to use 6V power supply.
