Resistance is defined as the resistance between terminal A to terminal B.
INL and DNL are measured at VW with VA = VDD and VB = VSS. (-202 devices VA = 4V).
MCP4021/23 only, test conditions are: IW = 1.9 mA, code = 00h.
MCP4022/24 only, test conditions are:

5: Resistor terminals A, W and B’s polarity with respect to each other is not restricted.
6: This specification by design
7: Non-linearity is affected by wiper resistance (RW), which changes significantly over voltage and temperature. See
Section 6.0 “Resistor” for additional information.
8: The MCP4021 is externally connected to match the configurations of the MCP4022 and MCP4024, and then tested.
