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 overvoltage and  
temperature.  
8: The MCP4XX1 is externally connected to match the configurations of the MCP45X2 and MCP46X2, 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 = VIHH, the IDD current is less due to current into the HVC/A0 pin. See IPU specification
