1. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
potentiometer.
2. 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.
3. MI = RTOT/63 or (R_H - R_L)/63, single pot
4. Typical = individual array resolutions.
5. Limits established by characterization and are not production tested.
6. Sample tested only.
7. Parts are 100% tested at +25°C. Over temperature limits established by characterization and are not production tested.
Power-up and Power-down Requirements
There are no restrictions on the power-up or power-down
conditions of V_CC and the voltage applied to the
potentiometer 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 ramp rate spec is always in effect.
