† Notice: Stresses above those listed under “Maximum
Ratings” may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at
those or any other conditions above those indicated in the
operational listings of this specification is not implied.
Exposure to maximum rating conditions for extended periods
may affect device reliability.
AC/DC CHARACTERISTICS
Electrical Specifications: Unless otherwise indicated, all parameters apply across the specified operating ranges.
TA = -40°C to +125°C, 2.1 kΩ, 5 kΩ, 10 kΩ and 50 kΩ devices. Typical specifications represent values for VDD = 5.5V, VSS = 0V,
TA = +25°C.

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: MCP4021/23 only, test conditions are: IW = 1.9 mA, code = 00h.
4: MCP4022/24 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: The MCP4021 is externally connected to match the configurations of the MCP4022 and MCP4024, and then tested.
