ESD SUSCEPTIBILITY
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 volts, which
readily accumulate on the human body and on test equipment, can discharge without detection.
Although the AD623 features proprietary ESD protection circuitry, permanent damage may still
occur on these devices if they are subjected to high energy electrostatic discharges. Therefore, proper
ESD precautions are recommended to avoid any performance degradation or loss of functionality.

Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This 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 maximum rating
conditions for extended periods may affect device reliability.
