100% production tested.
100% production tested at +25°C, and sample tested at
specified temperatures. AC testing done on sample
basis.
Sample tested only.
Parameter is guaranteed by design and characterization
testing.
Parameter is a typical value only.
All devices are 100% production tested at +25°C; sample
tested at temperature extremes.
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.

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 AD6640 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.
