What number is it correct to divide by your ADC counts as a first step in converting counts to voltage? For example, in a 10 bit ADC, is it correct to divide by 1024 or 1023?
I have always divided by 1024, which means that a full count would yield less than full scale voltage reading. I think this is a more accurate representation of the hardware, though, since there is usually an LSB of error. This is also what I've read in every datasheet, as well as various DSP literature and white papers from ADI and TI. Please prove me right (or wrong) with the detailed reasoning why!
