Power-up and Down Requirements

The are no restrictions on the power-up or power-down

conditions of VCC and the voltages applied to the poten-

tiometer pins provided that VCC is always more positive than

or equal to VH, VL, and VW, i.e., VCC VH, VL, VW.

The VCC power-up spec is always in effect.

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 (VH - VL)/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.
