TDA2822 mono amplifier circuit bridge 2W, General integrated amplifier circuit external components and need more larger heatsink. This paper presents a simple amplifier circuit, made easy. TDA2822 amplifier integrated circuits used in music players, portable DVD and other audio playback; power is not great but you can satisfy the requirements of the hearing, and the circuit is simple, good sound quality, wide voltage range of characteristics such as the amateur production Small amp better choice.
This is a small amplifier using TDA2822 chip. Including volume control. A 12 volt power supply is ideal for supply, which can be a source with batteries or transformer. It is not necessary to use heat sink.
The TDA2822D is a monolithic integrated circuit in 8 lead (SO-8) package. It is intended for use as a dual audio power amplifier in portable cassette players, radios and CD players.
