Mini Audio Amplifier Schematic Circuit Diagram
https://circuit-diagramz.com/mini-audio-amplifier-schematic-circuit-diagram/
Here is a simple and humble 2 Watts mini audio amplifier circuit suitable for small pocket radios and other portable audio gadgets. The circuit is based on Phillips Semiconductors IC TDA 7052. The amplifier can be run even from a 3V Mercury button cell. This makes it ideal for battery operated gadgets. The IC TDA7052 is a mono output amplifier coming in a 8-lead DI …

The amplifier circuit diagram shows a 2.5W * 2 stereo amplifier. You can also make a 5W mono amplifier out of it. (Check out the TEA2025 datasheet for more information on that) On the input side, you should use a dual potentiometer. A dual potmeter allows you to connect both the left and right channels on one potentiometer.
