Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Nonlinearity is defined from code 0 to code 65535 (full scale)
(end point INL, see Definitions section).
Note 3: Guaranteed by design. Not subject to test.

Note 4: To 1LSB. Unipolar mode. DAC switched between all 1s and all 0s.
Note 5: Digital Inputs at 0V or DV
Note 6: Measured at V
Note 7: When part powers up or when it is reset, the output is connected
to V
Note 8: Reset is active when any supply goes below this threshold.
Note 9: REFLO = 0V, REFHI = V
Only
