Typical Operating Characteristics

(TA = +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, fTOGGLE = 1MHz.

Note 4: Supply current taken while wiper position is fixed.
