ELECTRICAL CHARACTERISTICS (continued)
(V
Note 1: Linearity is defined in terms of the H-to-L code-dependent resistance.
Note 2: The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = V
Note 3: The DNL and INL are measured with the potentiometer configured as a variable resistor. H is unconnected and L = 0. The
Note 4: The wiper resistance is the worst value measured, injecting a current, I
Note 5: Digital timing is guaranteed by design.
