POWER-UP REQUIREMENTS (Power-up sequencing

Voltage should not be applied to the potentiometer
pins before V+ or V- is applied. The V ramp rate

specifi-cation should be met, and any glitches or slope
changes in the V line should be held to <100mV if

CC
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 , V+
CC
and V-reach their final value.
