AD6402ARS AD [Analog Devices], AD6402ARS Datasheet - Page 3

• Manufacturer Part Number: AD6402ARS
• Description: IF Transceiver Subsystem
• Manufacturer: AD [Analog Devices]

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 AD6402 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.
