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.
