*Absolute maximum ratings are limiting values, to be applied individually, and beyond
which the serviceability of the circuit may be impaired. Functional operability under
any of these conditions is not necessarily implied. Exposure of absolute maximum
rating conditions for extended periods of time may affect device reliability.

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 AD9851 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.
Application Note: Users are cautioned not to apply digital input signals prior to power-up of this device.
Doing so may result in a latch-up condition.
