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.
