Note 1: Resistance is defined as the resistance between the VREF pin and the VSS pin.
2: INL and DNL are measured at VOUT from Code = 20h (Zero Scale) through Code = 60h (Full Scale).
3: This specification by design.
4: Non-linearity is affected by wiper resistance (RW), which changes significantly over voltage and
temperature.
5: POR/BOR is not rate dependent.
6: Supply current is independent of VREF current.
7: See Section 7.1.3.
