(1) The relative accuracy or integral nonlinearity (INL) sometimes referred to as linearity error, is the maximum deviation of the output from
the line between zero and full scale excluding the effects of zero code and full-scale errors. Tested from code 10 to code 4095.
(2) The differential nonlinearity (DNL) sometimes referred to as differential error, is the difference between the measured and ideal 1 LSB
amplitude change of any two adjacent codes. Monotonic means the output voltage changes in the same direction (or remains constant)
as a change in the digital input code. Tested from code 10 to code 4095.
(3) Zero-scale error is the deviation from zero voltage output when the digital input code is zero.
(4) Zero-scale-error temperature coefficient is given by: E
