If it were that simple, the manufacturers would package it up into a single
I think there are two areas of interest. One is the obvious one that steps
on the high-order DAC won't cleanly map into a constant number of steps in
the low-order DAC.
The other is things like temperature shifts. You have to work out the specs
for both paths and take the worst one.
These are my opinions, not necessarily my employer's. I hate spam.
