Sorry for the delay, I use Google to access newsgroups and had not noticed your reply directed at me.

In that case, 1 nH (1mm) is close enough. Sometimes I do half that.

Would not care of it in this respect - unless I forgot about the fact planes also have inductance, same as the connecting path per mm.
This is all correct, of course. The separated plane is about 50mmx50mm sized, BTW; not such a huge thing to care about. In general, I accept most of the counterarguments; I am just saying split planes can be used sometimes _if_ one knows what he is doing.
Well my point of view includes about a month's worth initial testing and playing with the device - eventually, it does true 14 bits (does not just use a
14 bit ADC) at 0.5V fullscale input (risetimes in the 100s of nS range). Have yet to see this matched (although playing took part 5-6 years ago...).Dimiter
