Reading the note made me think of something else.
If it is an SAR, and you read to soon, the LSBs of the incomplete
conversion will always be the same. All ones or all zeros.
If it is a Sigma-Delta, and the input has noise
on it that is above the same rate,

Most of these older module use successive approximation converters. If you
read them too fast, you'll only get a partial conversion.
I'll second that. The ones I have seen most often (in another industry) were
Harris.

I was thinking that around this time, dual slop detectors were
becoming popular but it is unlikely this is your problem. If reading
a dual slope before conversion is complete, the value read would
be low in value, not just missing LSBs.
They were generally slower as well but often in the 16 or
