Note 2: The DNL and INL are measured with the potentiometer configured as a variable resistor. For the 3-terminal potentiometers
Note 3: The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = V
Note 4: Full-scale error is defined as
Note 5: Zero-scale error is defined as
Note 6: The wiper resistance is the worst value measured by injecting the currents given in Note 2 into W with L = GND.
Note 7: The device draws current in excess of the specified supply current when the digital inputs are driven with voltages between
Note 8: Wiper is at midscale with a 10pF capacitive load. Potentiometer set to midscale, L = GND, an AC source is applied to H,
Note 9: This is measured from the STOP pulse to the time it takes the output to reach 50% of the output step size (divider mode). It
Note 10: The programming current exists only during NV writes (12ms typ).
Note 11: Digital timing is guaranteed by design and characterization, and is not production tested.
Note 12: An appropriate bus pullup resistance must be selected depending on board capacitance. Refer to the I
Note 13: The idle time begins from the initiation of the stop pulse.
