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
