C AUT ION
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 AD1580 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. T herefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.

Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. T his is a stress rating only and functional
operation of the device at these or any other conditions above those indicated in
the operational section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

PACK AGE BRANDING INFORMAT ION
Four marking fields identify the device generic, grade, and date
of processing. T he first field is the product identifier. A “0”
identifies the generic as the AD1580. T he second field indicates
the device grade; “A” or “B.” In the third field a numeral or
letter indicates a calendar year; “5” for 1995, “A” for 2001. In
the fourth field, letters A-Z represent a two week window within
the calendar year; starting with “A” for the first two weeks of
January.
