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. Parameters Sym Min Typ Max Units 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.
