AD9851

–4–

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.

*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.
