Typical Operating Characteristics
(T
A
= +25°C, unless otherwise noted.)
Note 1: Up/Down Toggle Rate:
Note 2: Typical settling times are dependent on end-to-end resistance.
Note 3: Supply current taken while changing wiper tap, f
TOGGLE
= 1MHz.
Note 4: Supply current taken while wiper position is fixed.
