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.
