Resistance is defined as the resistance between terminal A to terminal B.
INL and DNL are measured at V
MCP4021/23 only, test conditions are: I
MCP4022/24 only, test conditions are:
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
Section 6.0 “Resistor” for additional information.
The MCP4021 is externally connected to match the configurations of the MCP4022 and MCP4024, and then tested.
