POWER UP AND DOWN REQUIREMENT
The are no restrictions on the sequencing of the bias supplies V
CC
, V+, and V- provided that all three supplies reach
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
CC
ramp rate spec is always in effect.
Notes:
(5) This parameter is periodically sampled and not 100% tested
(6) t
PUR
and t
PUW
are the delays required from the time the third (last) power supply (V
CC
, V+ or V-) is stable until the specific instruction can
be issued. These parameters are periodically sampled and not 100% tested.
(7) Sample tested only.
