This is an audio amplifier that can be used with a small 9 volt Battery Operated,Current use as little as 5 milliamps.And amplification up to 500 mW.
Which is sufficient to expand the sound from a sound about or the CD Walk Man out to the small speakers clearly.
When entering the power supply 9-volt circuit IC1 number LM386 amplifier IC size is 300-800 mW, Depending on the power supply circuit with,This is from 4-15 volts.
