Mini Stereo Audio Amplifier
This project is a Mini Stereo Audio Amplifier based on
TDA2822
IC.
Description
|
The dual low power amplifier built around TDA2822
8pin DIP. IC, it is mainly designed to use in
portable players, radios and other building block
project. A 3V supply can be used to drive headphones
providing 20mW in 32 Ohms per channel, and a 12V
power supply will provide 1W in 8 Ohm per channel
for small loudspeakers.
