POWER-UP AND POWER-DOWN
There are no restrictions on the power-up or power-
down sequencing of the bias supplies V_CC, V+, and V–
provided that all three supplies reach their final values
within 1msec of each other. However, at all times, the
voltages on the potentiometer pins must be less than
V+ and more than V–. The recall of the wiper position
from nonvolatile memory is not in effect until all
supplies reach their final value.
