NOTES:
1. All voltages are referenced to ground.
2. Valid for V
CC
=5V only.
3. Both UCx and DCx inputs are internally pulled up with a 50K
resistance.
4. Capacitance values apply at 25
°
C.
5. Input pulse width is the minimum time required for an input to cause an increment or decrement. If the UCx or DCx
inputs is held active for longer than 1 second, subsequent increments or decrements will occur on 100 ms intervals
until the inputs UCx, DCx are released to V
IH
. Timing tolerances for push–button control is
±
30%.
6. Inter–Channel Matching is used to determine the relative voltage difference in dB between the same tap position
on each potentiometer. The DS1802 is specified for
±
0.5 dB inter–channel matching.
7. Tap–to–Tap tolerance is used to determine the change in voltage between successive tap positions. The DS1802
is specified for
±
0.25 dB tap–to–tap tolerance.
8. Typical values are for t
A
=25
°
C and nominal supply voltage.
9. 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.
10.See Figure 6.
11. Absolute tolerance is used to determine measured wiper voltage vs. expected wiper voltage as determined by wiper
position. The DS1802 is bounded by a
±
1 dB absolute tolerance.
12.Maximum current specifications are based on clock rate, active zero–crossing detection, and push–button activa-
tion. See Figure 8 for clock rate vs. current specification.
13.Valid for V
CC
=3V or 5V.
14.See Figure 10.
15.Standby current levels apply when all inputs are driven to appropriate supply levels.
16.These parameters are characterized and not 100% tested.
