does anyone have the correct schematic for this IRS900d?
Is this PCB correct or cointaining errors?

I want to use IRFP250N for this AMP as it's shown in the IRS500 layout.
I wonder if irvynejay and anyone has made this AMP help me if there is some useful points.
I want to drive the Amp with -+60 volts . should i change some parameters like RSS resistors or others?
how much should it be?
please help me by your useful tips and experiences.
with Regards.

Hi nn20
greetings just make the pcb irvynejay posted IRP 250N works on 60 volts+/-
no change of components needed
warm regards

thanks to Mr lebon .and eager to read other new comments .
how much is the inductance of output inductor?
how many turns on that core( in video of irvynejay ) is needed?
i see 2 TO-220-package componnet at the bottom of PCB in that video.what are they?

oh excuse me . I completely forget the MOSFETs which should be connected to the bottom!
80uh and 0.47uf made LPF .is it?
is it the same for IRFP250N? (amplified square waves are the same but with different domains)

is the resistor error only prob with this pcb or something else also...and can i replace cd4049 with 4050????
the only way of knowing is for someone with better experience with class d to etch the pcb, build and test the amp.
the irs2000/3000d pcb didn't even come with a proper schematic so probably it would be even more helpful if someone would be good enough to trace the pcb and make a schematic out of it. that would allow people with better experience to browse and check for errors as it's quite hard to check for design error just by looking at the pcb traces.
and no you cannot replace it with cd4050 as you need an inverter.
I have made rs900. now it has a problem. one the Mosfets isn't driven and it's working by just one of these mosfets. both of them are ok. what to do?
plz dude post your schematics...need to know the reasons why i'm not getting the things worked up with my pcd
i had almost connected every part i guess so with irs3000d.....i would be powering it with +/-40volts.....plz give any suggestions if i would have to check out with anything serious with this pcb and schematic
is there any substitute for cd4049 as i dont have it at my place...any perfect one with same pin out plz help me out...i need to test the design today itself...
i already posted i don't have schematic,, that's the only file i have i made the amp with out schematic
