Note 1: Linearity is defined in terms of the H-to-L code-dependent resistance.
Note 2: The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = VDD and L = 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. H is unconnected and L = 0. The
wiper terminal is driven with a source current of 200µA at VDD = +3V and 400µA at VDD = +5V.
Note 4: The wiper resistance is the worst value measured, injecting a current, IW = VDD/RHL into terminal W.
Note 5: Digital timing is guaranteed by design.
