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
Note 4: The wiper resistance is the worst value measured by injecting the currents given in Note 3 into W_ with L_ = GND. R
