Correct, but it DOES define the best Dmax that the system can achieve.  The
system is ONLY as good as its weakest point.

There was a confusion between input voltage range of the A/D and the
resolution within that range.  They are separate issues, and only one is
Dmax, the other is irrelevant (if designed properly).
