WebThe DNL resolution is 1/ (Number of samples per code). So, if you want to know your DNL to 0.1 LSB accuracy, you need 10 samples per code. So if you have a 12-bit ADC, you need 10*2^10 = 10,240 samples minimum. Usually you probably want more like 0.01 LSB accuracy so you would need 102,400 samples.
