IRC-2000 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.
Added temp sensors on which will protect the amp on unstable conditions.
