Power-up and Down Requirements
There are no restrictions on the power-up or power-down
conditions of V_CC and the voltages applied to the
potentiometer pins provided that V_CC is always more
positive than or equal to V_H, V_L, and V_W, i.e., V_CC ≥ V_H, V_L,
V_W. The V_CC ramp rate spec is always in effect.

Notes: (6) Typical values are for T_A = 25°C and nominal supply voltage.
(7) This parameter is 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.
