    Analog Devices -> Microchip. Otherwise, yes, it is a nice app note.

    Editor’s note: Thanks! For some reason, I saw the AN number and got it into my head that the A stood for Analog. Nice to know someone out there is reading. 🙂

    I hadn’t seen the Microchip article.

    I have (unsuccessfully so far) tried this to just get a good sounding sine wave for a CW keyer. I am going to keep trying.

    Here is a longer article from TI about PWM Digital-to-Analog. It also covers filtering and does some comparison to a DAC. I haven’t absorbed it all yet.
