CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily accumulate
on the human body and test equipment and can discharge without detection. Although the ADM8830
features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high
energy electrostatic discharges.Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
