definitions

zero error

The absolute value of the difference between the actual analog voltage at the 01H-to-00H transition and the

ideal analog voltage at that transition.

overall error

The magnitude of the deviation from a straight line between the endpoints of the transfer function.

differential nonlinearity

The maximum deviation of an analog-value change associated with a 1-bit code change (1 clock pulse) from

its theoretical value of 1 LSB.
