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. See This Schematic and datasheet IC AN313 below : Datasheet IC AN313 Vcc = 12-20 V Pout = 2x3 W RL = 8 Ohm Ft = 40hz -18Khz Icco = 40 mA Package = TABS6-16 Manufactered = MATSUSHITA Or you can call , Datasheetnya IC AN313
