= +25˚C. ) (Note 1)
Note 1: All devices are 100% production tested at T
Note 2: DNL and INL are measured with the potentiometer configured as a voltage-divider (Figure 1) with H = V
Note 3: R-DNL and R-INL are measured with the potentiometer configured as a variable resistor (Figure 1). DNL and INL are mea-
Note 4: The wiper resistance is the worst value measured by injecting the currents given in Note 3 in to W with L = GND. R
Note 5: Drive HA with a 1kHz GND to V
Note 6: The wiper-settling time is the worst case 0 to 50% rise time, measured between tap 0 and tap 127. H = V
Note 7: Digital timing is guaranteed by design and characterization, not production tested.
