*Stresses greater than those listed under Absolute Maximum Ratings may cause
permanent damage to the device. T his is a stress rating only; functional operation
of the device at these or any other conditions above those indicated in the
operational section of this specification is not implied. Exposure to absolute

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 AD1821 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
T he AD1821 latchup immunity has been demonstrated at
≥
+100 mA/–80 mA on all pins when
tested to Industry Standard/JEDEC methods.
WARNING!
