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 AD1954 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.
