PIC24EP512GP202 D/A -- Does it exist?

The MICROCHIP ADVANCED PART SELECTOR indicates that the PIC24EP512GP202 contains 1 D/A, but the datasheet makes no mention of it.  Can anyone confirm whether it does or does not have a D/A converter?

    I can't confirm, but I would trust the datasheet over the MAPS database...

    Often, when MAPS shows a DAC on PIC24, it's "hidden" in the comparator, as is the case with your PIC.

    OK.  Looking in the Family Reference, under the Comparator section, I found this: "The CVREF output pin can be used as a simple Digital-to-Analog output..."
    So the DAC is actually the selectable comparator voltage reference output.

    Possibly not relevant in this case (I've not bothered to look at the documents myself) but be a little cautions about taking information from the FRM with respect to a specific MCU.
    The FRM is great in telling you in detail how to use all of the possibilities that occur within a family but you must also cross-check with the MCU data sheet that the specific device actually provides that functionality in the first place.
