The converter latency becomes a larger and larger fraction of the total latency as the other components of latency are reduced. Whether those numbers are considerable or not depends on how sensitive to latency you are (or your application is.) I have a vague recollection of conversion delays being on the order of tens of sample times, but it depends on the chips in use as well as the design of the circuits in which they reside.
Certainly when latencies were measured in the tens of milliseconds, the ADA component was in the noise; now that we have fast enough machines and I/O subsystems to cut the buffering down, the conversion latency is a sizable fraction of the total.
