the set {-3, -2, -1, 1, 2, 3}. There will be no missing code around 2048, and in spite of the missing code the ADC will be monotonic
at all times so that a response to a slowly increasing input will always be a slowly increasing output. Around the one code that is
missing, the neighbour codes will look wider in the DNL plot. The spectra will show spurs on the level of -78dBc for a full scale
input for chips that have the missing code issue.

On the average every ADC will have one missing code, most likely to appear around 2048 +/- n*512 where n can be a value in
Typical numbers given by abs(Mean) / (85 - 25).
