Note 1:
Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range has
been calibrated.
Note 2:
See Typical Operating Characteristics.

.
Note 5:
REFOUT supplies typically 2.5mA under normal operating conditions.
Note 6:
External load should not change during the conversion for specified accuracy.
Note 7:
