0,5 WATT MINI AMPLIFIER TDA1015T ELECTRONIC DIAGRAM
0,5 WATT MINI AMPLIFIER TDA1015T ELECTRONIC DIAGRAM
Chances are you'll want this amplifier portable. Batteries do the trick fine, but you won't get much power out of a couple of 1.5V cells. Unfortunately the size of a decent amount of battery power will mean that the overall size of this amp will be much bigger and for that there are more benefits to be had using a device like the TDA7052 or TDA2822 for stereo.
Quick ref data of TDA1015T Chip
