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.
NOTES
1Absolute 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.
2Typical thermal impedances (52-terminal LQFP); θJA = 33°C/W; θJC = 11°C/W.
These measurements were taken on a 6 layer board in still air with a solid ground
plane.

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 AD6644 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.
WARNING!
