Note 1:
Resistance is defined as the resistance between terminal A to terminal B.

.
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
MCP4XX1
is externally connected to match the configurations of the
MCP41X2
and
MCP42X2,
and
then tested.
9:
POR/BOR is not rate dependent.
10:
Supply current is independent of current through the resistor network.
