A company right here (POLYTRON) used it, but the filter inductor is very hot, it has good protection and sounds better than usual class-D. It is cheap and very small indeed, my friend designed for them. If there someone near only, may I could help.
He also told me that this thing could very easily driven real 120Wrms into 4ohm.

Hi authlxl,

I think TDA8953/4 would be a better choice for proamp.

TDA8950 works stable and sound powerful.only our experience.

Thanks!

TDA8920 & TDA8950 is pin to pin compatible.

How does the sound quality compare with both?

Some sources even say its even better than LM3886.

I'm just wondering, anyone have tried?
