NOTES: 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 (see text).
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.
3. Zero-scale error is the deviation from zero-voltage output when the digital input code is zero (see text).
4. Zero-scale-error temperature coefficient is given by: E

TC = [E

5. Gain error is the deviation from the ideal output (V
ref
– 1 LSB) with an output load of 10 kΩ excluding the effects of the zero-scale
error.
6. Gain temperature coefficient is given by: E
G
TC = [E

7. Zero-scale-error rejection ratio (EZS-RR) is measured by varying the V
DD
from 4.5 V to 5.5 V dc and measuring the proportion of
this signal imposed on the zero-code output voltage.
8. Gain-error rejection ratio (EG-RR) is measured by varying the V
DD
from 4.5 V to 5.5 V dc and measuring the proportion of this signal
imposed on the full-scale output voltage after subtracting the zero-scale change.
