Note
Resistance is defined as the resistance between terminal A to terminal B.
INL and DNL are measured at V
MCP44X1 only.
MCP44X2 only, includes V
Polarity of resistor terminals A, W and B, with respect to each other, is not restricted.
This specification by design.
Non-linearity is affected by wiper resistance (R
temperature.
The MCP44X1 is externally connected to match the configurations of the MCP44X2, and then tested.
POR/BOR is not rate dependent.
