2 Watts audio power bridge amplifier IC TDA2822 – volume control

| | , ,

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.

  1. friend thanks for the circuit helped me a lot .. I can say it is called the program that where you have the components. are very real, I would greatly appreciate digest the name of that program thanks in advance

  2. cordial saludo:
    amigo gracias por el circuito me sirvió de mucho.. me pueden decir como se llama el programa ese donde tiene los componentes. se ven muy reales le agradecería mucho que me digieran el nombre de ese programa de antemano gracias

  3. Hi Toni Thankx for the circuit . But Can you tell me That how to Deliver maximum Wattage From this 2822 amp By providing it 3.7 Volts , As your circuit is based upon 12 Volts , Please solve my this query .Thak you

  4. Hi, I’ve been looking for a SPICE model for the TDA2822 without any luck. I’ve done numerous web searches and checked the ST site. I’ve even emailed their Tech. Support without any response.
    Do you have any ideas where I might find one?
    Regards
    Graeme
