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 AD1881A 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.
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 t he
operational section of this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
Stresses greater than those listed under Absolute Maximum Ratings may cause
