3: MCP43X1 only.
4: MCP43X2 only, includes V

.
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 (R
W
), which changes significantly over voltage and
temperature.
8: The MCP43X1 is externally connected to match the configurations of the MCP43X2, and then tested.
9: POR/BOR is not rate dependent.
10: Supply current is independent of current through the resistor network.
