POWER UP AND DOWN REQUIREMENT
The are no restrictions on the sequencing of the bias supplies V , V+, and V- provided that all three supplies reach
CC
their final values within 1msec of each other. 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.The V ramp rate spec is always in effect.

Notes: (5) This parameter is periodically sampled and not 100% tested
(6) t
and t
are the delays required from the time the third (last) power supply (V , V+ or V-) is stable until the specific instruction can

be issued.These parameters are periodically sampled and not 100% tested.
