A.C. OPERATING CHARACTERISTICS
(Over recommended operating conditions unless otherwise specified)
POWER-UP AND DOWN REQUIREMENTS
At all times, voltages on the potentiometer pins must be less than ±V
CC
. The recall of the wiper position from nonvola-
tile memory is not in effect until the V
CC
supply reaches its final value. The V
CC
ramp rate spec is always in effect.
A.C. TIMING
Notes: (6) Typical values are for T
A
= 25°C and nominal supply voltage.
(7) This parameter is periodically sampled and not 100% tested.
(8) MI in the A.C. timing diagram refers to the minimum incremental change in the V
W
output due to a change in the wiper position.
