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 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.
