2. 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.
3. 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.
4. Zero-scale error is the deviation from zero voltage output when the digital input code is zero.
5. Zero-scale-error temperature coefficient is given by: EZS TC = [EZS (Tmax) – EZS (Tmin)]/Vref
×
106/(Tmax – Tmin).
6. Gain error is the deviation from the ideal output (2Vref – 1 LSB) with an output load of 10 k
excluding the effects of the zero-error.
7. Gain temperature coefficient is given by: EG TC = [EG(Tmax) – EG (Tmin)]/Vref
×
106/(Tmax – Tmin).
