(VDD = +2.7V to +5.25V, H = VDD, L = GND, TA = -40
°C to +85°C. Typical values are at VDD = +5.0V, TA = +25°C, unless otherwise
noted. See Figure 1.) (Note 7)

Note 1: The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = VDD and L = GND. The
wiper terminal is unloaded and measured with a high-input-impedance voltmeter.
Note 2: The DNL and INL are measured with the potentiometer configured as a variable resistor. H is unconnected and L = GND.
For the 5V condition, the wiper terminal is driven with a source current of 80A for the 50k
Ω configuration, 40A for the
100k
Ω configuration, and 20A for the 200kΩ configuration. For the 3V condition, the wiper terminal is driven with a source
current of 40A for the 50k
Ω configuration, 20A for the 100kΩ, and 10A for the 200kΩ configuration.
Note 3: The wiper resistance is measured using the source currents given in Note 2. For operation to VDD = 2.7V, see Maximum
Wiper Resistance vs. Temperature in the Typical Operating Characteristics.
Note 4: The device draws higher supply current when the digital inputs are driven with voltages between (VDD - 0.5V) and (GND +
0.5V). See Supply Current vs. Digital Input Voltage in the Typical Operating Characteristics.
Note 5: Wiper at midscale with a 10pF load (DC measurement). L = GND; an AC source is applied to H; and the W output is mea-
sured. A 3dB bandwidth occurs when the AC W/H value is 3dB lower than the DC W/H value.
Note 6: The programming current operates only during power-up and NV writes.
Note 7: Digital timing is guaranteed by design and characterization, and is not production tested.
Note 8: Wiper-settling time is the worst-case 0% to 50% rise-time measured between consecutive wiper positions. H = VDD, L =
GND, and the wiper terminal is unloaded and measured with a 10pF oscilloscope probe.
