8. Power–up time is the time for all push–button 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 V

=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.
