Notes:
1. Voltage is referenced to ground.
2. Valid at 25
oC only.
3. Wiper resistance is a function of operating characteristics. See section “POTENTIOMETER WIPER
RESISTANCE AND CHARGE PUMP CONSIDERATIONS” for RWIPER characteristics.
4. Absolute linearity is a measure of wiper output voltage versus expected wiper voltage as determined
by wiper position.
5. Relative linearity is a measure of the output deviation between successive potentiometer tap points.

Notes:
1. Voltages are referenced to ground.
2. Under certain low voltage conditions VILMAX may have to be reduced to as much as 0.5V to always
guarantee a presence pulse.
3. VPUP is the external 1-Wire pull-up voltage.
4. Input load is to ground.
5. Input current when an auxiliary VDD supply is used and the charge pump is turned OFF.
6. Input current when an auxiliary VDD supply is used and the charge pump is turned ON.
