Resistance is defined as the resistance between terminal A to terminal B.
INL and DNL are measured at V
MCP40D18 device only, includes V
Resistor terminals A, W and B’s polarity with respect to each other is not restricted.
This specification by design.
Non-linearity is affected by wiper resistance (R
temperature.
POR/BOR is not rate dependent.
Supply current is independent of current through the resistor network
