POWER UP REQUIREMENTS (Power Up sequencing

can affect correct recall of the wiper registers)

The preferred power-on sequence is as follows: First

Voltage should not be applied to the potentiometer pins

cation should be met, and any glitches or slope

0.1V for more than 1 second before powering up again

should not reverse polarity by more than 0.5V. Recall of

reach their final value.
