Deviation of actual DAC output when all 0s are loaded to the DAC from the ideal output of –4.096 V.

Deviation of actual DAC output span from the ideal span of 8.191 V.

PSSR is tested by changing the respective supply voltage by

±5%.

For 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.

Reference input resistance is code dependent.

Typical settling time with 1000 pF capacitive load is 8

µs.

Does not include reference power.
