Note 1: Linearity is defined in terms of the HX to LX code-dependent resistance.

Note 2: The DNL and INL are measured with the potentiometer configured as a voltage-divider with HX = VDD and LX = 0. The wiper

terminal is unloaded and measured with an ideal voltmeter.

Note 3: The DNL and INL are measured with the potentiometer configured as a variable resistor. HX is unconnected and LX = 0. At

VDD = +5V, the wiper terminal is driven with a source current of 400µA for the 10kΩ configuration, 80µA for the 50kΩ config-

uration, and 40µA for the 100kΩ configuration. At VDD = +3V, 200µA/40µA/20µA for 10kΩ/50kΩ/100kΩ configurations,

respectively.

Note 4: The wiper resistance is the worst value measured by injecting into WX, a current IW = VDD / RHL.

Note 5: Digital timing is guaranteed by design.
