-=-=- An innovative positive feedback scheme is used to boost the current drive capability of the output stage. This allows the LMV793/LMV794 to source more than 40 mA of current at 1.8V supply. This also limits the performance of these parts as comparators, and hence the usage of the LMV793 and the LMV794 in an open-loop configuration is not recommended.

What the heck does that mean? Why would it be okay in linear (closed loop) operation, and in saturated operation, but not in open loop operation?
Maybe it does weird bouncy stuff when recovering from saturation, so the comparator output edge isn't monotonic?
The elephant in the room is the input differential +/- 0.3V range, which means they put diodes across it. Why the hell would they do that on a CMOS amp?!
(I'm considering this part for a current shunt amplifier, so these wrinkles shouldn't be a problem, at least, but it worries me that there should ever be even a single quirk, in a stupid freaking op-amp, in 2017.)
