1. The programming current operates only during power-up and non-volatile memory writes.
2. DNL and INL are measured with the potentiometer configured as a voltage-divider with HIGH = V
3. DNL and INL are measured with the potentiometer configured as a variable resistor. HIGH is unconnected and
4. The wiper resistance is measured using the source currents given in Note 3. The number is the worst case
5. The device draws higher supply current when the digital inputs are driven with voltages between (V
6. Wiper at midscale with a 10pF load (DC measurement) V
7. Wiper-settling time is the worst-case 0 to 50% rise-time measured between successive wiper positions. HIGH =
8. This parameter is not tested but ensured by characterization.

LOW = GND. For the 5V condition, the wiper terminal is driven with a source current of 400µA @ 10kΩ, 80µA @
50kΩ, 40µA @ 100kΩ. In 3V conditions, the wiper terminal is driven with a source current of 200µA @ 10kΩ,
