Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although WARNING! the AD7858/AD7858L features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions ESD SENSITIVE DEVICE are recommended to avoid performance degradation or loss of functionality.
