7. Tap–to–Tap tolerance is used to determine the change in voltage between successive tap positions.

The DS1800 is specified for ±0.5 dB tap–to–tap tolerance. From position 0 to position 112 (+20 dB to

–27 dB). From position 113 to position 127, the DS1800 is specified for ±1 dB tap–to–tap tolerance.

8. Power–up time is the time for all pushbutton inputs to be stable and active once power has reached a

valid level, 2.7V min.

9. Absolute tolerance is used to determine wiper voltage versus expected wiper voltage as determined by

wiper position. The DS1800 is bounded by a ±0.5 dB absolute tolerance from position 0 to position

112 and ±1 dB tolerance from position 113 to position 127.

10. Maximum current specifications are based on clock rate, active zero–crossing detection, and push–

button activation.

11. Valid for VCC =3V or 5V.

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.
