Mini Stereo Audio Amplifier using IC TEA2025

This is a very simple schematic diagram of mini stereo audio amplifier build based the main power IC of TEA2025. This IC support both single audio channel and stereo audia channel. There will be 2x2.5W for stereo channel and 5W for mono channel with bridge mode. TEA2025 is a monolithic integrated audio amplifier in a 16-pin plastic dual in line package. It is designed for portable cassette players and radios, featured with Working Voltage down to 3V, Few External components, High Channel isolation, Voltage gain up to 45dB(Adjustable with external resistor), Soft clipping and Internal Thermal protection.
