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 AD621 features proprietary ESD pro-

tection circuitry, permanent damage may still occur on these

devices if they are subjected to high energy electrostatic dis-

charges. Therefore, proper ESD precautions are recommended

to avoid any performance degradation or loss of functionality.
