_______________________________________________________________________________________ 3
Note 1: All devices are 100% production tested at TA = +25°C. 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 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 mea-
sured 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 400A for the 10kI configuration, 80A for the 50kI configuration, and 40A for
the 100kI configuration. For VDD = +2.6V, the wiper terminal is driven with a source current of 200A for the 10kI configu-
ration, 40A for the 50kI configuration, and 20A for the 100kI configuration.
Note 4: The wiper resistance is the worst value measured by injecting the currents given in Note 3 in to 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.
ELECTRICAL CHARACTERISTICS (continued)
(VDD = +2.6V to +5.5V, VH_ = VDD, VL_ = GND, TA = TMIN to TMAX, unless otherwise noted. Typical values are at VDD = +5V, TA
= +25C. ) (Note 1)
