TMS320F28P550SJ: How many DAC channels does this MCU have?

Tool/software:

Hi,

I'm evaluating TMS320F28P550SJ as a candidate for our next product. When I was going through the data sheet, I noticed that some contradicting information on the DAC. Can someone confirm with you whether there are two 12-bit DACs on this chip or one DAC? Does DACB exist here?

Thanks,

Frank

    Frank,

    Thanks for the question, we have recently updated the DS(TMS status) on TI.com to help clear this up.

    There is 1 12-bit Buffered DAC: pin name DACA_OUT

    There is ability to bring out the internal DAC from CMPSS1 low comparator to a pin: pin name CMP1_DACL

    CMP1_DACL was previously referred to as DACB_OUT in the TMX DS, but since this is not a full/standalone DAC we re-named to CMP1_DACL to avoid confusion.

    These 2 DACs have different specs in the DS, and use of CMP1_DACL removes the use of the low side comparator of CMPSS1 as well.

    Let us know if you have additional questions.

    Best,

    Matthew
