Circuit power audio amplifier stereo 2x 1 watts tda2822 - Dual low-voltage power amplifier With PCB

TDA2822 is an ideal Op amp for low output applications. It is a good choice as a preamplifier in stereo high power amplifier circuits. It has two inputs and two outputs which can deliver 250 milli watts output power. The amplifier circuit with in the IC is well set for noise free operation. Outputs can be directly coupled to the speakers through the decoupling capacitors.

  1. i tried to make this one, and partly it succeeded, i have to much of ground noise, how can i eliminate that?
    i dont have a potentiometer at hand so i did hook it up directly wonder if the ground noise is related or not, and if related, is there a way to use this circuit without an potentiometer? i would like to hook directly in and have an out so that there is no volume control

  2. Good morning, sir.

    I would just like to ask: is there a way to make this amplifier have a 2 x 2 watts output?

    I’m not an electrician and I know very little about electronic circuits so I would appreciate it very much if you could assist me with this regard.

    Thank you very much.
