D.C. OPERATING CHARACTERISTICS
(Over the recommended operating conditions unless otherwise specified.)
Notes:
(1) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used
as a potentiometer.
(2) Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potenti-
ometer. It is a measure of the error in step size.
(3) MI = RTOT/255 or (V

(4) Max. = all four arrays cascaded together, Typical = individual array resolutions.
ENDURANCE AND DATA RETENTION
CAPACITANCE
POWER-UP TIMING
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

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.
