Note 1:

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

INL and DNL are measured at VW with VA = VDD and VB = VSS.

MCP44X1

only.

MCP44X2

only, includes VWZSE and VWFSE.

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 (RW), which changes significantly over voltage and

temperature.

The MCP44X1 is externally connected to match the configurations of the MCP44X2, and then tested.

POR/BOR is not rate dependent.

10:

Supply current is independent of current through the resistor network.

11:

When HVC/A0 = VIHH, the IDD current is less due to current into the HVC/A0 pin. See IPU specification.
