    All parameters apply across the specified operating ranges unless noted.
    VDD = +2.7V to 5.5V, 5 k, 10 k, 50 k, 100 k devices.
    Typical specifications represent values for VDD = 5.5V, TA = +25°C.

    Conditions
    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: MCP4XX1 only.
    4: MCP4XX2 only, includes VWZSE and VWFSE.
    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.
    8: The MCP4XX1 is externally connected to match the configurations of the MCP41X2 and MCP42X2, and
    then tested.
    9: POR/BOR is not rate dependent.
    10: Supply current is independent of current through the resistor network.
