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. (-202 devices VA = 4V).

MCP4011/13 only, test conditions are: IW = 1.9 mA, code = 00h.

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 (RW), which changes significantly over voltage and temperature. See

Section 6.0 “Resistor” for additional information.

8: For voltages below 2.7V, refer to Section 2.0 “Typical Performance Curves”.

9: The MCP4011 is externally connected to match the configurations of the MCP4012 and MCP4014 and then tested.
