POWER-UP TIMING
POWER-UP AND POWER-DOWN
There are no restrictions on the power-up or power-down sequencing of the bias supplies V
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.
Notes: (5) This parameter is periodically sampled and not 100% tested
