What about the performance of the IRAUDAMP7S?

Hi:
I found a ref design from IR with their IRS2902 and IRF4019, which can give a maximum of 500W output. I think it is enough to drive my ATC SCM19. Is there anyone who has experience using this chip? What about the performance? Thank you!?

I don't own one of these amps yet but have been following discussions, this thread has some interesting info:

there are a couple of ready made modules available. One from Connexelectronic and one from Zoe_tsang on Ebay.

Iv'e heard they are very quite, would be interesting to get some more reports though.

I designed my own2092 + 4227 500 watt amplifier.
I was very pleased with the sound.
I did have a couple of minor problems.
1/ Got a loud pop through speaker on power down (some modules did and others didnt despite having same components.)
2/ Got the 2092 resetting if driven hard into clipping. Not strictly a problem as it was pumping out more than 500 watts in hard clipping.

What about your circuit? Any difference from the reference design? Thank you!

I used the datasheet circuit.
