Tda2822 Amplifier With Tone Control. 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. The tda2822m is an 8 pin dil package but the older tda2822 is a 14 pin variant with greater power output but a larger size.
The amplifier circuit with in the ic is well set for noise free operation. It will work with a 12v power supply and will have bass treble and mid frequency control so that the output audio can be adjusted as required. Tda2822 amplifier integrated circuits used in music players portable dvd and other audio playback.
It is a good choice as a preamplifier in stereo high power amplifier circuits.
The original integrated is jrc4558 from the company new japan radio co but those who say only c leave good quality like other brands. You may have heard of the tda2822 or tda2822m before but for those who haven t it is a small power amplifier that will drive two channels. It has two inputs and two outputs which can deliver 250 milli watts output power. In this project we will design an active tone control circuit powered by an op amp with a pcb design.
