Note 1: Resistance is defined as the resistance between terminal A to terminal B.
2: INL and DNL are measured at VW with VA = VDD and VB = VSS.
3: MCP4018 device only, includes VWZSE and VWFSE.
4: Resistor terminals A, W and B’s polarity with respect to each other is not restricted.
5: This specification by design.
6: Non-linearity is affected by wiper resistance (RW), which changes significantly over voltage and
temperature.
7: POR/BOR is not rate dependent.
8: Supply current is independent of current through the resistor network
