Notes:
1. Integral non-linearity (INL) 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).
2. Differential non-linearity (DNL) is the difference between the measured and ideal 1LSB amplitude change
of any adjacent two codes. A guarantee of monotonicity means the output voltage changes in the same
direction (or remains constant) as a change in digital input code.
3. Zero code error is the voltage output when the DAC input code is zero.
4. Gain error is the deviation from the ideal full scale output excluding the effects of zero code error.
5. Power supply rejection ratio is measured by varying AVDD from 4.5V to 5.5V and measuring the
proportion of this signal imposed on the zero code error and the gain error.
6. Zero code error and Gain error temperature coefficients are normalised to full scale voltage.
7. Output load regulation is the difference between the output voltage at full scale with a 10k
Ω load and 2kΩ
load. It is expressed as a percentage of the full scale output voltage with a 10k
Ω load.
