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 posi-
tion. 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 activa-
tion.
11. Valid for V
CC
=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.
