... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD8522 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 ...

... LDB pin. Serial data register bit Sf/Hd must be low for this mode effect. The second mode of operation is software-load which is de- signed to minimize the number of control lines connected to the AD8522. In this mode of operation the LDA and LDB pins act as one control input taking the present contents of the serial Typical Performance Characteristics 5 ...
