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:
MCP40D18 device only, includes VWZSE and VWFSE.
4:
Resistor terminals A, W and B’s polarity with respect to each other is not restricted.
5:
This specification by design.
6:
Non-linearity is affected by wiper resistance (RW), which changes significantly over voltage and
temperature.
7:
POR/BOR is not rate dependent.
8:
Supply current is independent of current through the resistor network
