Wiper Increment Toward Terminal A
Wiper Decrement Toward Terminal B
Wiper Position Fixed
Common Mode (MODE = 0) moves both wipers together either
UP or DOWN the resistor array without changing the relative
distance between the wipers. Also, the distance between both
wipers is preserved if either reaches the end of the array. Inde-
pendent Mode (MODE = 1) allows user to control each RDAC
individually: DACSEL = 0 sets RDAC1; DACSEL = 1: sets
RDAC2.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD5222 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
