Conditions

Note 1:

Resistance is defined as the resistance between the VREF pin and the VSS pin.

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.
