NOTES:
7. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
potentiometer.
8. Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potentiometer. It is
a measure of the error in step size.
9. MI = RTOT/63 or (V_H - V_L)/63, single pot.
10. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by
characterization and are not production tested.
Power-up and Down Requirements
The are no restrictions on the power-up or power-down
conditions of V_CC and the voltages applied to the poten-
tiometer pins provided that V_CC is always more positive than
or equal to V_H, V_L, and V_W, i.e., V_CC ≥ V_H, V_L, V_W.
The V_CC power-up spec is always in effect.
