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 AD6645 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.

WARNING!

ESD SENSITIVE DEVICE

EXPLANATION OF TEST LEVELS

Test Level

I.

100% production tested.

II.

100% production tested at 25

∞C and guaranteed by design

and characterization at temperature extremes.

III. Sample tested only.

IV. Parameter is guaranteed by design and characterization

testing.

V.

Parameter is a typical value only.

*Absolute maximum ratings are limiting values to be applied individually and beyond which the serviceability

of the circuit may be impaired. Functional operability is not necessarily implied. Exposure to absolute

maximum rating conditions for an extended period of time may affect device reliability.
