TIMING CHARACTERISTICS
(V
V
Note 1: 100% production tested at T
Note 2: The DNL and INL are measured for the voltage-divider with H_ = V
Note 3: The DNL and INL are measured with 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 with a 10pF load on W_. Transition code from 0 to 495 and measure
