The q denotes specifications which apply over the full operating
temperature range.
Note 1: Nonlinearity is defined from the first code that is greater than or
equal to the maximum offset specification to code 4095 (full scale).
Note 2: Load is 5kΩ in parallel with 100pF.
Note 3: DAC switched between all 1s and the code corresponding to VOS
for the part.
Note 4: Digital inputs at 0V or VCC.
