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.  
WARNING!
