NOTES
1_{Stresses above those listed under Absolute Maximum Ratings may cause perma-}
nent damage to the device. This is a stress rating; functional operation of the device ₈
at these or any other conditions above those listed in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.

maximum power dissipation of the package, and maximum applied voltage across
any two of the A, B, and W terminals at a given resistance. Please refer to TPC 31

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 AD5200/AD5201 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!
