Analog to digital converter general: worst case resolution / noise free bits

How to calculate the number of noise free bits ( = "worst case resolution") of
an Analog to digital converter?


You asked how many stable bits you expect to see or are you referring to the
deviation from the ideal transfer function. To find out the number of noise
free bits, you will need to take a look at the histogram plots in the datasheet
to see how the output code varies for a dc input voltage.
