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 AD7390/AD7391 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.
The AD7390 contains 588 transistors. The die size measures 70 mm
Line 1 contains ADI logo symbol and part number. Line 2 contains grade and date code YWW. Line 3 contains the letter G plus the 4-digit lot number.

OUT
Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
specification is not implied. Exposure to the above maximum rating conditions for
extended periods may affect device reliability.
