470 mWatts audio amplifier for portable applications
A very simple audio amplifier electronic project can be designed using this circuit diagram . This audio amplifier project can be used in small audio circuits that not require much audio power .
This audio amplifier electronic project will provide a 470 mwatts output poThis circuit has less than 2% distortion and is flat within 3 dB from 15Hz to 130kHz .
As you can see in the schematic circuit , this power amplifier use just three transistors and some other common electronic parts .
This electronic project must be powered from a 12 volt DC power supply .wer in a 16 or 32 ohms load .
