–
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily ac cu mu late on
the human body and test equipment and can discharge without detection. Although the AD9851 features
proprietary ESD pro tec tion circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD pre cau tions are rec om mend ed to avoid per for mance
deg ra da tion 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.

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.
