ELECTRICAL CHARACTERISTICS (continued)
(V
unless otherwise noted.)
Note 1: Linearity is defined in terms of the H
Note 2: The DNL and INL are measured with the potentiometer configured as a voltage divider with H
Note 3: The DNL and INL are measured with the potentiometer configured as a variable resistor. For the 3-terminal potentiometer
Note 4: The wiper resistance is the worst value measured by injecting into W
Note 5: Digital timing is guaranteed by design.
