±15V, 128-Tap, Low-Drift Digital Potentiometers ELECTRICAL CHARACTERISTICS (continued)
(VDD = +15V, VSS = -15V, VCC = +5V, VH = VDD, VL = VSS, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C, unless otherwise noted.)

Note 1:
The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = VDD and L = VSS. The wiper terminal is unloaded.
Note 2:
The DNL and INL are measured with the potentiometer configured as a variable resistor. H is unconnected and L = VSS. The wiper terminal is driven with a source current of 80µA for the 50kΩ configuration and 40µA for the 100kΩ configuration.
Note 3:
The wiper resistance is measured assuming the source currents given in Note 2.
Note 4:
The device draws current in excess of the specified supply current when the digital inputs are driven with voltages between (VCC - 0.5V) and (GND + 0.5V). See Supply Current vs. Digital Input Voltage in the Typical Operating Characteristics section.
Note 5:
Guaranteed by design and characterization.
