*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.

EXPLANATION OF TEST LEVELS

Test Level

I – 100% Production Tested.

III – Sample Tested Only.

IV – Parameter is guaranteed by design and characterization

testing.

V – Parameter is a typical value only.

VI – Devices are 100% production tested at 25°C and

guaranteed by design and characterization testing for

industrial operating temperature range.

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 AD9857 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.
