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.
