Schematic Audio Amplifier with IC AN313

This schematic very suitable applied on small speakers. Because the maximum output is 3W and the minimum voltage is 12 Volt  , this will make speaker does not damage quickly. If you use speaker with impedance 8 Ohm , you must make parallel circuit speaker don't use series circuit.
