Terminology
Resolution
The DAC resolution is defined by the number of distinct analog levels corresponding to the
number of bits it uses.
N-bit resolution -> 2N distinct analog levels
Differential Nonlinearity (DNL) error
The variation in analog step sizes away from 1 LSB by any two adjacent codes. Usually,
gain and offset errors have been removed.
Integral Nonlinearity (INL)
It is the deviation of actual transfer response from a straight line. Usually, INL error is
referred to as the maximum INL error.
