Tda2822m Amplifier Circuit Diagram. In addition to ic tda2822m ic1 it uses four capacitors c1 through c4 two potmeters vr1 and vr2 and two speakers. We often feel the requirements of headphone amplifier circuit for amplifying our small audio devices like mp3 players walkmans cell phones etc.

The ic can be operated in both btl and stereo mode. Another part of the circuit is a tda2822m amplifier which is used to amplify the melody sound of the um66. Circuit of the stereo amplifier using tda2822.

Tda2822m is a small audio amplifier ic available in 8 pin dip package.

The circuit works off 3v dc. The output of um66 will be very low if you will not use any amplifier with it therefore to increase the output sound of the melody we have used the tda2822m ic which is a low voltage audio amplifier available in 8 pin dip and provides 1w output with 9v dc using 8 ohms 1w speaker. When building small battery operated audio projects like bell buzzer or radio circuits etc. Sta540 ic car amplifier circuit tda7377 upgrade duration.
