Resistance is defined as the resistance between terminal A to terminal B.
INL and DNL are measured at V
MCP4XX1 only.
MCP4XX2 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.
The MCP4XX1 is externally connected to match the configurations of the MCP45X2 and MCP46X2, and
then tested.
POR/BOR is not rate dependent.
