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.

MI ⁽⁸⁾
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.
