Note 1: Resistance is defined as the resistance between terminal A to terminal B.
2: INL and DNL are measured at V_W with V_A = V_DD and V_B = V_SS.
3: MCP44X1 only.
4: MCP44X2 only, includes V_WZSE and V_WFSE.
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.
8: The MCP44X1 is externally connected to match the configurations of the MCP44X2, and then tested.
9: POR/BOR is not rate dependent.
10: Supply current is independent of current through the resistor network.
11: When HVC/A0 = V_IHH, the I_DD current is less due to current into the HVC/A0 pin. See I_PU specification.
