Resistance is defined as the resistance between terminal A to terminal B.
INL and DNL are measured at V_W with V_A = V_DD and V_B = V_SS. (-202 devices V_A = 4V).
MCP4011/13 only, test conditions are: I_W = 1.9 mA, code = 00h.
MCP4012/14 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 (R_W), which changes significantly over voltage and temperature. See
Section 6.0 “Resistor” for additional information.
8: For voltages below 2.7V, refer to Section 2.0 “Typical Performance Curves”.
9: The MCP4011 is externally connected to match the configurations of the MCP4012 and MCP4014 and then tested.
