EXPLANATION OF TEST LEVELS

Test Level

I–

100% production tested.

II

–

100% production tested at +25

°C and sample tested at

specified temperatures. AC testing done on sample basis.

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; sample

tested at temperature extremes.

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.
