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
pushbutton 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.
