Audio Amplifier Based TDA1554 IC
This audio amplifier circuit works up to 2 x 22Watt with main power IC TDA1554. The circuit has only very few components and works best with a 4 Ohm speaker.
IC TDA1554 must be connected to a heat sink. A computer cabinet fan can also be used in addition. Any way better the cooling better the performance.The circuit roughly draws 6A current at 12 V at full volume.So the power supply must be any thing more than 6A.Up to 18 V can be used
