Software/electrical engineering - quantisation step-size?

Question

could someone help me with the following question, please

Given the MAX1104 can handle a range of input levels from GND to Vdd (where Vdd = 5v) and it has an 8 bit, “shifted” binary analogue to digital (ADC) and digital to analogue converter (DAC). What is the quantisation step-size of the DAC/ADC?

Answer 1

q = V/(2^N - 1) where V is max voltage range and N is number of digital bits, so q would be 5/(256-1) = 1.96 mV.
