EXPLANATION OF TEST LEVELS
Test Level
I
–
100% production tested.
100% production tested at +25
°
C, and sample tested at
specified temperatures. AC testing done on sample basis.
II –
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; guaranteed
by design and characterization testing at temperature
extremes for 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 AD9023 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recom-
mended to avoid performance degradation or loss of functionality.
