* Stresses greater than 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 section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

CAUTION
ESD (Electrostatic discharge) sensitive device. Electrostatic charges as high as 400 V readily
accumulate on the human body and Test equipment and can discharge without detection.
Although the AD1959 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.
