IRCore2000 1000W Class-D Amplifier Blank PCB
Mono Class-D amplifier based on IRAUDAMP9.
The design implements a heavy duty gate driver circuit (FZT853 + FZT953) for operating 2 pairs of IRFB4227 mosfets.
The module is capable of delivering clean 600W into 4 ohms and 1000W burst into 2 ohms load.
Quality solder joints are very important to achieve optimum performance, so the builder should be highly skilled in soldering and should have an experience in building DIY amplifiers.
