Some 16 bit ADC's specifications has "No missing code: 14 bits min", like ADI's AD7656. I want to know where the 14 bits locate in the 16 bits. Does it mean the high 14 bits?
According to the definition of 'No missing code', the missed code can be one or more of the possible 2^n binary code. Assume a 16 bit ADC with 1 bit missing code, no matter where the missed code locate, i can safely use it as a 15 bit ADC, right?
And i want to know the relation of DNL and 'No missing code', i think if a 16 bit ADC specified with DNL = +/-4 LSB, i can assume the no missing code is 14 bit, right ?
