I've been watching ADCs more than DACs, but I'll bet they follow the same
pattern.
For ADCs, there seem to be two markets with two sets of features. One type
has DC specifications that are interesting for this discussion, things like
drift and linearity.
The other type focuses on AC specifications. The typical application is
audio or radar. The data sheet usually includes FFT pictures. Specs include
things like ENOB, effective number of bits. (It's usually better at less
than max frequency.)
