PSSR is tested by changing the respective supply voltage by
±5%.
4
For best performance, REF should be greater than AGND + 2 V and less than V
DD
– 0.6 V. The device operates
with reference inputs outside this range, but performance may degrade.
5
Reference input resistance is code dependent.

Typical settling time with 1000 pF capacitive load is 8
µs.
