    i found schematic from this link https://320volt.com/ir2153-class-d-amfi-devresi-400w/
    interesting, but I'm more interested in class AB than class D

    at least I know ir2153 can be a class d amplifier , I tried simulation but I can't make it better
    maybe Norazmi has a better design

    Interesting ! you can do even frequency modulation by varying the IR frequency with a transistor from pin 3 to GND. The output filter passes the low frequencies more and HF less.

    Class D is interesting too, you can get big power easily and the sound quality is still very good !

    This is good enough for class D. Can I get from you the IR2153, irf640 and lm311 ltspice symbols ?
