AD9244-EVAL Analog Devices, AD9244-EVAL Datasheet - Page 5

• Manufacturer Part Number: AD9244-EVAL
• Description: 14-Bit/ 40/65 MSPS Monolithic A/D Converter
• Manufacturer: 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 AD9244 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recom-
mended to avoid performance degradation or loss of functionality.

*Stresses above those listed under Absolute Maximum Ratings may cause permanent
damage to the device. This is a stress rating only; functional operation of the device at
these or any other conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum ratings for extended periods
may affect device reliability.
