Hi Harold,

I had reason to go looking for a PIC with a DAC recently and found
that some of the DSPIC series do indeed have DACs. They are a bit
hidden as their main purpose seems to be as a reference for the
onboard comparators, but they can be output to external pins, and they
have very respectable update rate and other specs. I think the maximum
number of DACs on one chip is 2.
