0 5 WATT MINI AMPLIFIER TDA1015T SCHEMATIC DIAGRAM
A volume control is included in schematic. Log type is required and 4k7 to 10k is about right. A dual pot is needed if you plan on using two TDA1015s to complete a stereo amp.
Chances are youll want this amplifier portable. Batteries do the trick fine, but you wont 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.
