INL and DNL are measured at VOUT from Code = 00h (Zero-Scale) through Code = 3Fh (Full-Scale - 1). This specification by design. Nonlinearity is affected by wiper resistance (RW), which changes significantly over voltage and temperature. POR/BOR is not rate dependent. Supply current is independent of VREF current.
