POWER-UP AND POWER-DOWN

There are no restrictions on the power-up or power-

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.
