Digital Potentiometers
4
Note 1: The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = V
Note 2: The DNL and INL are measured with the potentiometer configured as a variable resistor. H is unconnected and L = GND.
Note 3: The wiper resistance is measured using the source currents given in Note 2.
Note 4: The device draws current in excess of the specified supply current when this input is driven with a voltage greater than 0.7
Note 5: Wiper at midscale with a 10pF load. Potentiometer set to midscale, L = GND, an AC source is applied to H, and the output
Note 6: The programming current operates only during power-up and NV writes.
Note 7: SCL clock period includes rise and fall times t
Note 8: Wiper settling time is the worst-case 0% to 50% rise time measured between consecutive wiper positions. H = V
Note 9: An appropriate bus pullup resistance must be selected depending on board capacitance. Refer to the document linked to
Note 10: The idle time begins from the initiation of the stop pulse.

wiper terminal is unloaded and measured with a high-input-impedance voltmeter.
For the 5V condition, the wiper terminal is driven with a source current of 80µA for the 50kΩ configuration, 40µA for the
100kΩ configuration, and 20µA for the 200kΩ configuration. For the 3V condition the wiper terminal is driven with a source
current of 40µA for the 50kΩ configuration, 20µA for the 100kΩ configuration, and 10µA for the 200kΩ configuration.
