ESD 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 this product 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.
WARNING—Please note that this device in its current form does not meet Analog Devices’ standard requirements for ESD as
measured against the charged device model (CDM). As such, special care should be used when handling this product, especially in
a manufacturing environment. Analog Devices will provide a more ESD hardy product in the near future at which time this warn-
ing will be removed from this data sheet.
