TDA1554HQ Hi-Fi Power Amp IC Power that is is simple, easy and cheap. The output power is 22W (THD 10%) by channel (Bridged) at load (Speaker) 2 Ohm. which certainly did not disappoint the sound, treeble not sensitizing the ear (soft) and mid powerful.
Schematic TDA1554HQ Power Amp :
Supply voltage must not exceed 18Vdc, or IC is not going to work (probably will burn). and 17V is quite safe and appropriate use Heatsink (quite big) or use a cooling fan so that IC is working optimally.
PCB Layout :
