    Hey everyone,

    I am working on a project where I have to design a Digital Class D Amplifier with PSR.

    I came across this chip:

    But I am not sure how to connect it. Do you use the outputs PSR_DATA as negative feedback? What about stability considerations?

    What is your tech background? Basic class D is really easy, this chip seems like major overkill. Of course, I've never used it, and I wonder how many people have.

    Class-D is a rapidly evolving science.
    There is an extremely good website, DIYAudio.com which specializes on audio and has a forum named "Class D", which you should browse for ideas.

    Bill M: I'm right now reading a very good book about the Apollo project from an engineering perspective. In it, it says that Joe Shea, which was development director during the early years had that same saying ..... It has the meaning, that engineers will always find ways to improve a design, and thus never let it go, thus delaying a product release.
    Anyways, after the Apollo 1 fire, he was removed from the director role.
