TIMING CHARACTERISTICS

4
Note 1: 100% production tested at T
Note 2: The DNL and INL are measured with the device configured as a voltage-divider with H = V
Note 3: The DNL_R and INL_R are measured with D.N.C. unconnected and L = V
Note 4: The wiper resistance is measured using the source currents given in Note 3.
Note 5: The device draws higher supply current when the digital inputs are driven with voltages between (V
Note 6: Wiper settling test condition uses the voltage-divider configuration with a 10pF load on W. Transition code from 00000 00000
