Parameters Sym Min Typ Max Units Conditions
Note 1: Resistance is defined as the resistance between terminal A to terminal B.
2: INL and DNL are measured at V

SS
.
3: MCP4XX1 only.
4: MCP4XX2 only, includes V
WZSE
and V
WFSE
.
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 overvoltage and
temperature.
8: The MCP4XX1 is externally connected to match the configurations of the MCP45X2 and MCP46X2, and
then tested.
9: POR/BOR is not rate dependent.
10: Supply current is independent of current through the resistor network.
11: When HVC/A0 = V
IHH
, the I
DD
current is less due to current into the HVC/A0 pin. See I
PU
specification.
