Note 3:
Load is 5k
in parallel with 100pF.
Note 4:
DAC switched between all 1s and the code corresponding to V
OS
for the part, i.e., LTC1451: code 18; LTC1453: code 30.
Note 5:
Digital inputs at 0V or V
CC
.
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2:
Nonlinearity is defined from the first code that is greater than or
equal to the maximum offset specification to code 4095 (full scale).
