TDA1554HQ Hi-Fi Power Amp

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 :

Note: pin labeled N.C. is Not Connected or Not Connected (anywhere).

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.
