The only thing that the TBolt can report is the number that it feeds to the 
DAC.

I expect the actual voltage out would vary with temperature, supply voltage, 
age, and whatever.  Add in the reference voltage if that's not included in the 
DAC.

I haven't looked at DAC data sheets recently.  How many of the modern ones 
have a set of small graphs showing parameters like that?
