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 128 to code 65535 (full scale).
See Applications Information.
Note 3:
DAC switched between all 1s and all 0s. V
FS
= 4.096V.
Note 4:
Digital inputs at 0V or V
CC
.
Note 5:
Part is clocked with pin toggling between 1s and 0s, CS/LD is low.
Note 6:
Reference can be overdriven (see Applications Information).
Note 7:
Guaranteed by design. Not subject to test.
Note 8:
Guaranteed by correlation for other reference and supply
conditions.
