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 5k Ω 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. |
