Terminology

Resolution

The DAC resolution is defined by the power factor of 2, which defines the number of

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.
