The DAC has an INL of about 20 or so LSBs. DNL is +-2LSB. Since it is a 14 bit DAC, is it safe to say that the DAC is monotonic for 13 bit use? (Since DAC is monotonic if DNL is not below -1LSB)
And secondly, what INL is considered good enough for DAC? Of course it should be as close to 0.5LSB, however, is there any other information provided by INL that needs to be considered?
