CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily ac cu mu ate on
the human body and test equipment and can discharge without detection. Although the AD1954 features
proprietary ESD pro ec ion circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD pre cau ions are rec om mend ed to avoid per or mance
deg a da ion or loss of functionality.
