POWER UP REQUIREMENTS
(Power Up sequencing
can affect correct recall of the wiper registers)
The preferred power-on sequence is as follows: First
V
CC
, then the potentiometer pins, R
H
, R
L
, and R
W
.
Voltage should not be applied to the potentiometer pins
before V+ or V- is applied. The V
CC
ramp rate specifi-
cation should be met, and any glitches or slope
changes in the V
CC
line should be held to <100mV if
possible. If V
CC
powers down, it should be held below
0.1V for more than 1 second before powering up again
in order for proper wiper register recall. Also, V
CC
should not reverse polarity by more than 0.5V. Recall of
wiper position will not be complete until V
CC
, V+ and V-
reach their final value.
