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.
