This portable audio amplifier circuit electronic project is based on TDA1015 integrated audio amplifier circuit designed for portable radio and recorder applications.
TDA1015 portable audio amplifier circuit delivers up to 4 W in a 4 ohms load impedance with a 12 volts power supply . If we are using a 6 volts power supply we can obtain a output power around 1 watt or a 2.3 watts output power with a 9 volts power supply .
