What is the relationship between these three specifications of ADC?

Hi neoflash,
In principle, there is no relationship between DNL/INL on the one hand and the resolution on the other hand.
When we compare non-idealities or errors of an ADC with a number of bits, we mean that the error is as large as the quantization error of an ideal ADC with that given number of bits...
