Tda2003 Ic Circuit Diagram. The ic can easily deliver 10w to a 4 ohms load speaker. Which it uses the supply voltage from 12 volt car battery.
Circuit diagram of 3w to 6w audio amplifier using tda2003 the amplifier ic delivers 3w output power using a 6v 500ma power supply and 6w output power using a 12v 500ma power supply with an 8 ohm 6 watt speaker. It provides a high output current capability up to 3 5a very low harmonic and cross over distortion. Symbol parameter test conditions min.
But this circuit adapted for use at home by listening to change power supply to 18 volts.
Which it uses the supply voltage from 12 volt car battery. It provides a high output current capability up to 3 5a very low harmonic and cross over distortion. Connect audio input signal to non inverting pin of tda2003 ic. Pin 1 of tda2003 is the input terminal which is connected to ground through a 100 kilo ohm resistor.
