The pre-built version of the amplifier kit allows you to focus more on product design. The stereo amplifier kit is supplied with all the resistors, volume control, capacitors, power switch & IC holder fitted. Students just need to finish it by connecting the jack lead, speakers & power clip to the board.
This deluxe amplifier kit can be used with any personal stereo equipment, including MP3 players. The kit has a volume control & power LED. It can be powered by a batteries connected to the PP3 clip or a DC power module can be plugged in when the batteries automatically disconnect and the power supply is used. The kit can be powered off a 2V to 15V supply, though the volume is better with a higher supply. It uses a TDA2822M audio amplifier IC which can output 1W per channel.
PCB dimensions: 62mm x 50mm.
It has a PP3 battery clip and can run off any voltage from 2 to 15 volts.
It works nicely off a 9V battery (not supplied) or if you want to run it of the mains why not try our 12V wall power unit.
