D.C. OPERATING CHARACTERISTICS (Over the recommended operating conditions unless otherwise specified.)

ENDURANCE AND DATA RETENTION

CAPACITANCE

POWER-UP TIMING

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

specifi-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

and V-reach their final value.
