Amplifier circuit diagram using tda2030:
Amplifier circuit diagram using tda2030. this is a 14 watts 4-ohms audio amplifier. this circuit can run with 6-0-6 to 18-0-18 voltage. here need dual voltage positive negative and the ground voltage. normally this circuit is used in the 2.1 sound system. it’s a mono circuit. if we need a stereo amplifier then we have to use 2 circuits. the IC needs a heat sink.
TDA2030 ic is a powerful audio IC. it’s a class AB amplifier.
