Note 1: 100% production tested at T
Note 2: INL linearity is guaranteed from code 15 to code 255.
Note 3: Connect a resistor from FSADJ_ to GND to adjust the full-scale current. See the Reference Architecture and Operation section.
Note 4: Settling time is measured from (0.25 x full scale) to (0.75 x full scale).
Note 5: The device draws higher supply current when the digital inputs are driven with voltages between (V
