7. Tap–to–Tap tolerance is used to determine the change in voltage between successive tap positions.
8. Power–up time is the time for all pushbutton inputs to be stable and active once power has reached a
9. Absolute tolerance is used to determine wiper voltage versus expected wiper voltage as determined by
10. Maximum current specifications are based on clock rate, active zero–crossing detection, and push–
11. Valid for V
12. Standby current levels apply when all inputs are driven to appropriate supply levels.
13. These parameters are characterized and not 100% tested.
14. See Figure 9.
15. Valid at 25 C only.
