Note 1: The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = VDD and L = VSS. The
wiper terminal is unloaded.
Note 2: The DNL and INL are measured with the potentiometer configured as a variable resistor. H is unconnected and L = VSS.
The wiper terminal is driven with a source current of 80A for the 50k
Ω configuration and 40A for the 100kΩ configuration.
Note 3: The wiper resistance is measured assuming the source currents given in Note 2.
Note 4: The device draws current in excess of the specified supply current when the digital inputs are driven with voltages between
(VCC - 0.5V) and (GND + 0.5V). See Supply Current vs. Digital Input Voltage in the Typical Operating Characteristics section.
Note 5: Guaranteed by design and characterization.
