class D amplifier

Question

Hi Guys I want to build a class D amplifier at home. The power output could be 50-100W or even less. I need a working schematic of the amplifier, please post if you guys have worked with any. The most important part is that schematic needs to work as the final product.

I found a schematic from All about circuit which is a little complicated for me.

Thanks

The IRS20124 chip looks to be about as simple as it can be done.... Or maybe an IRS2092 IRS2092 .

The car actually adds complexity. It's a rough environment for electronics - electrical and mechanical.

Hi, yes, your question was clear. If you like to build one for home use or in car use, this is not easy and it give you much more complicated if you haven't the right measurement Equipments. You cannot build it "just for fun". Sorry. The links i posted you is the best what you can get for building it via schematics. Because you have also the GERBER files as well and the BOM list for all the needed devices. Also the PCB must be build well for a good sound. That datasheets you can download it as well. As Jan said, for car use, it adds much more complexity. It's really better that you buy an amp what you like for your "roar-cubes" ... Gerald ---
