NOTES
1 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.
2 Typical thermal impedances (64-lead LQFP); JA = 54°C/W. These measurements
were taken on a 4-layer board in still air, in accordance with EIA/JESD51-7.

EXPLANATION OF TEST LEVELS
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 100% production tested at 25°C; guaranteed by design and
characterization testing for industrial temperature range; 100%
production tested at temperature extremes for military devices.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily accumulate on
the human body and test equipment and can discharge without detection. Although the AD9238 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.
