ELECTRICAL CHARACTERISTICS (continued)
(VDD = +2.6V to +5.5V, VH_ = VDD, VL_ = GND, TA = -40NC to +125NC, unless otherwise noted. Typical values are at VDD = +5V,
TA = +25NC.) (Note 1)
Note 1: All devices are 100% production tested at TA = +25NC. Specifications overtemperature limits are guaranteed by design
and characterization.
Note 2: DNL and INL are measured with the potentiometer configured as a voltage-divider (Figure 1) with H_ = VDD and L_ = 0V.
The wiper terminal is unloaded and measured with an ideal voltmeter.
Note 3: R-DNL and R-INL are measured with the potentiometer configured as a variable resistor (Figure 1). DNL and INL are
measured with the potentiometer configured as a variable resistor. H_ is unconnected and L_ = GND. For VDD = +5V, the
wiper terminal is driven with a source current of 400FA for the 10kI configuration, 80FA for the 50kI configuration, and
40FA for the 100kI configuration. For VDD = +2.6V, the wiper terminal is driven with a source current of 200FA for the
10kI configuration, 40FA for the 50kI configuration, and 20FA for the 100kI configuration.
Note 4: The wiper resistance is the worst value measured by injecting the currents given in Note 3 into W_ with L_ = GND. RW =
(VW - VH)/IW.
