NOTES

1 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 listed in the operational

sections of this specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect device reliability.

2 If the AD7884/AD7885 is being powered from separate analog and digital

supplies, AVSS should always come up before VSS. See Figure 12 for a recom-

mended protection circuit using Schottky diodes.

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 AD7884/AD7885 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.

WARNING!
