Question Have anyone ever seen this CLASS-D PCB ?

I saved this picture on my computer about 1 month ago but I can't remember where can I find its schematic, I remembered only it used hip4080a for H-bridge mosfet driver.

Or anyone can suggest me for a new project of Class-D which used hip4080a/81a ?

Question Second question...

If I want to use HIP4081A instead of HIP4080A, How do I do (change pins or cut pin) ? and I can't see what's different from them why ?

the PCB you've copied is from a guy named Simon-Emanuel Waid (from Austria in Europe as a work at the university of Vienna) and shows a PCB of his "400W Klasse D Endstufe".
The URL is still online at "http://stud1.tuwien.ac.at/~e0326790/projekte/klassed/klassedde.htm".
Just klick on the right at the line with "Platinenlayouts (453k)", which will be the 2nd download possibility. His complete work can be seen by using the 1st download ("Meine Facharbeit: Schaltpläne und genaue Beschreibung der Funktionsweise (3304k)"), but if you're not so familiar with the german language you might run into some sort of trouble.
I might be pleased to translate his work - unfortunately he's the copyright holder and I will respect this and I'm not going to translate his work without a written permission from him. Nevertheless you might have the chance to ask him for an already translated script.

With kind regards
