TDA2822 is a dual low voltage power amplifier using in portable players or portable radio cassette players. The main advantage of this audio amplifier is, it works with starting voltage of 1.8 to 15V DC supply. It can able to deliver the output wattage of 250 milli watts. This amplifier IC is most suitable for pre audio amplifier section because of low Crossover Distortion. The TDA2822 IC can use to build stereo or bridge mode audio amplifiers.
The IC package have two input and output terminals, it can easily deliver the 250 milli watts. The total package of integrated circuit is designed for low noise or distortion in output speaker.
