    Hi Flotul

    I already saw a '317 as a couple of KHz PWM amplifier ( yes ON/OFF !!! ) ... OK ... precisely ON/1.25v ...

    Seems it's also already used in classA amplifiers !!! ( see National Datasheet )

    Just have a nice filtering for the PWM out of the Pic and it will work just as you want !!!

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    Default ?

    Alain,

    I downloaded the datasheet and quickly read it.

    Could you give me a little more info about what you mean by "a couple of kHz amplifier"?

    Sougata,

    Your link just gives everything I need . I thought I could make something with less components; I'm very short in space.

    Hi, flotul

    I just mean the ref pin is driven by a 1kHz 12v p.p. square wave !!!

    The use is a variable switching supply for model Trains ...
