1Deviation of actual DAC output when all 0s are loaded to the DAC from the ideal output of –4.096 V.
2Deviation of actual DAC output span from the ideal span of 8.191 V.
3PSSR is tested by changing the respective supply voltage by ±5%.
4For best performance, REF should be greater than AGND + 2 V and less than VDD – 0.6 V. The device operates
with reference inputs outside this range, but performance may degrade.
5Reference input resistance is code dependent.
6Typical settling time with 1000 pF capacitive load is 8 µs.
7Does not include reference power.
