WARNING!

ESD SENSITIVE DEVICE

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 AD7475/AD7495 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.
