A stereo audio amplifier is a simple electronic circuit that can work as a sound amplifier. It consists of the core element TDA8560Q IC, which has a large number of built-in features that allow the circuit to be efficient and minimized. Therefore, with fewer components, you can create an effective electronic circuit that is simple and portable. You can use this circuit to boost the output to greater values.
However, in this circuit TDA8560Q works like a stereo audio amplifier. Therefore, this circuit is more suitable for making car speakers. You just have to pick up the following elements and make the right circuit by using the schematic diagram shown below.

Stereo Audio Amplifier Circuit
Working Explanation
This circuit operates at a voltage of 6V – 18V DC, which can be ideally used for a portable audio amplifier. The circuit includes TDA8560Q IC with thirteen pins having distinct features and functions. Two speakers are attached to the output terminals of the IC while the mode select options give you the facility to operate, standby, and mute. The other terminals of the IC are ground to avoid the short circuit. The complete model is a simple yet effective sound amplifier.
