EXPLANATION OF TEST LEVELS

Test Level

I – 100% production tested.

II – 100% production tested at 25°C, and sample tested at

specified temperatures.

III – Sample tested only.

IV – Parameter is guaranteed by design and characterization

testing.

V – Parameter is a typical value only.

VI – All devices are 100% production tested at 25°C. 100%

production tested at temperature extremes for extended

temperature devices; sample tested at temperature

extremes for commercial/industrial devices.

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 AD9058 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.
