That looks cool
Woow
Thats impressive, but no one is making that amplifier from DIY guys around.
May be becasue:-
* Its SMD
* Very costy to make it as proto
* Not any DIY can make double sided PCBs?
* Not all DIY can assemble and solder SMD?
Thats an application note amplifier, and the internet is full with these schematics and no one pays attention to them. its just an application note.
Even those who made amplifiers with IRS2092 had serious problems with noise and sound quality, DUE poor PCB layout may be? or due critical selection of parts? and output Mosfets maybe?
This will be DIY, but nothing from the critical components will be shown to DIY, WHY?
Because it will be copied LIKE hell in no time. Specially the output devices.
The MOSFETS!
Good luck friend

Good points there - I always consider these application notes as a "good start"...
I never told they are bad. I said its just an application note

Micro, please as U own this forum, I'd expect a bit more polite "welcome" as it was my first post... I didn't want to argue with Your design, I've mentioned amp9 as a good start or reference, never said its good or bad, just as a reference...
Apologise

Yep! I apologize for you :w)
Welcome!
I am sorry also, I didnt mean any thing, it was all about making a simple DIY class-D amplifier , thats all.
You are free to argue

I realized that my comment was not clear... I meant to say:
* Good/valid points raised by MicrosiM
* Application notes are good starting points, but nothing beyond that - i.e. one needs to "work" on the design a bit.
:UP:
Yep that's true,
But I would like to add, that big manufacturers, like crown for example when they make D amp using IRS2092 they get some special information's and details about the chip from IR company, that its not available for DIY, other wise there will be no difference between the two designs.
However, critical values of components and a special wiring of that chip will make it sound better and
+ Critical selection of Mosfets will make that Amplifier deliver 750W @ 2R stable.
Thanks dudaindc !
