AC/DC CHARACTERISTICS (CONTINUED)
Electrical Specifications: Unless otherwise indicated, all parameters apply across the specified operating ranges.
TA = -40°C to +125°C, 2.1 kΩ, 5kΩ, 10 kΩ and 50 kΩ devices. Typical specifications represent values for VDD = 2.7V to 5.5V,
VSS = 0V, TA = +25°C.

Conditions
Note 1:
Resistance is defined as the resistance between terminal A to terminal B.
2:
INL and DNL are measured at VW with VA = VDD and VB = VSS. (-202 devices VA = 4V).
3:
MCP4011/13 only, test conditions are: IW = 1.9 mA, code = 00h.
4: MCP4012/14 only, test conditions are:
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.
