CAUTION

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 AD8614/AD8644 features proprietary ESD protection circuitry, permanent dam-

age may occur on devices subjected to high energy electrostatic discharges. Therefore, proper

ESD precautions are recommended to avoid performance degradation or loss of functionality.

WARNING!
