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 potentiom-
eter. It is a measure of the error in step size.
(3) MI = RTOT/63 or (RH - RL)/63, single pot
(4) Max. = all four arrays cascaded together, Typical = individual array resolutions.
ENDURANCE AND DATA RETENTION
CAPACITANCE
POWER-UP TIMING
POWER-UP AND POWER-DOWN
There are no restrictions on the power-up or power-down sequencing of the bias supplies VCC, V+, and V- 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.
Notes: (5) This parameter is periodically sampled and not 100% tested
(6) tPUR and tPUW are the delays required from the time the third (last) power supply (VCC, 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.
