ELECTRICAL CHARACTERISTICS (continued)
(VDD = +1.7V to +5.5V, VH_ = VDD, VL_ = 0, TA = TMIN to TMAX, unless otherwise noted. Typical values are at VDD = +1.8V,
TA = +25NC.) (Note 1)
Note 1: All devices are 100% production tested at TA = +25NC. Specifications over temperature 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_ =
GND. The wiper terminal is unloaded and measured with a high-input-impedance 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 = +1.7V, the wiper terminal is driven with a source current of 150FA for the
10kI configuration, 30FA for the 50kI configuration, and 15FA for the 100kI configuration.
Note 4: The wiper resistance is the value measured by injecting the currents given in Note 3 into W_ with L_ = GND.
RW_ = (VW_ - VH_)/IW_.
Note 5: Drive HA with a 1kHz GND to VDD amplitude tone. LA = LB = GND. No load. WB is at midscale with a 10pF load.
Measure WB.
Note 6: The wiper-settling time is the worst-case 0 to 50% rise time, measured between tap 0 and tap 127. H_ = VDD, L_ = GND,
and the wiper terminal is loaded with 10pF capacitance to ground.
Note 7: Digital timing is guaranteed by design and characterization, not production tested.
