The Infineon product paper application part dont show the use of output inductors - why used here?

It does. You look in the wrong paper but indeed it is marketing versus reality. Search for "MA12070 output filter".
The chip can be used without filter when your loudspeakers are unpractically close to the amplifier.

OK!
First attempt yielded no sound. But no smoke either 😉
I'll reconnect the rest of the amp an see if it plays....

Ooo, perhaps I have been hoxed 🙂
It plays now. Big(er) sound stage. However noisy even with 18 ohm in series with the horn. Does the noise make it sound bigger? 🙂
This was the sale: https://www.amazon.se/Bluetooth-för...dd-b7c2-0067d097f723&pd_rd_i=B0BRHL74MG&psc=1
BUT ACTUALLY NOT THAT SELLER - MY SELLER IS GONE .... 8-o
And Ma12070 was not in the time, but still in the description.
I think you might be right @irribeo - I will get that RCA connector off... brutal way... 😉

There could be another part with 8 pins a side, maybe it only looks like 8 pins? Or did you see the chip now?
Go TNT to DIY... try MA5332.... It's a tpa killer...
My last diy amp delighted me!!!
A little too powerful for libraries ... But the sound is in line with MA12070 chips ...
Infineon are the king of class D chips... In my opinion for now!
The only chips that rival my big class AB amp.🙂🙂👍
🙂🙂🙂Graphics don't interest me much...my ears and my feelings are my only judge...
Michel Xiao's MA532 cards are really stunning, he followed the Infineon specs, for me ... it's the most powerful chip, power level and musical feeling ...
The measures for me .... Are only tricks and masturbation of engineers.
listen to your ears!!!!😊

Mmmm that is quite bad. Nice layout but no MA12070 hidden underneath that RCA connectors....It says MA12070 in the description indeed. Bummer.
