25 of 27

NOTES:

1. Voltage is referenced to ground.

2. Valid at 25

3. Wiper resistance is a function of operating characteristics. See section “POTENTIOMETER WIPER

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.
