the sources of THD that you have found in conventional UcD topology?
Have he? Have I missed something?
IE6 don't show your file .png 😡 (totally black picture)
For other forum members with the same problem:
I had to save the file and open it with a non-M$$$$soft image viewer
OT: It's time to change....

I am planning to build a 500W class D amplifier to drive subwoofer based on this Zetex ZXCD1210. Anybody has experienced in it before?

Hi RX5!
whta parts do you mean? i think that onle one part hard to find is doubled output fets, maybe driver.

Bender,
Im in the Philippines... much URBAN than other, and yeah, the real hard && impossible to get are the Dual MOSFETS, the mosfet driver and the "AD" input....
The mosfets could probably be subd with single N-Ch mosfets...
anyways, nice that you had that thing going...
how about adding a protection circuitry to it?? or how about converting the driver chip to a discrete one? 😉
Cheers!

hi Luka, thanks for reply.
i put ad825 at input, because i have ones for free 🙂
you can replace it by tl071, ne5531 or other soic8 single opamp without any perfomance derating 😉
Most of them are pin-to-pin compatible.
It's easy to trace pcb for usual to-220 case fet, if you want, i can do it.

ps: what kind of protection do you mean, OVP, UVP, OCP, OTP? my project is only simple sample of DIY amp not for commercial use.
