ELECTRICAL CHARACTERISTICS (continued)
(V
unless otherwise noted.)
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. For the 3-terminal potentiometers
Note 4: The wiper resistance is the worst value measured by injecting the currents given in Note 3 into W_ with L_ = GND. R
Note 5: Device draws higher supply current when digital inputs are driven with voltages between (V
Note 6: Wiper-Settling Time is the worst case 0% to 50% rise-time measured between consecutive wiper positions. H_ = V
Note 7: Digital timing is guaranteed by design.
