NOTES

1Stresses 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.

2Transient currents of up to 100 mA will not cause SCR latch-up.

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 AD7943/AD7945/AD7948 feature proprietary ESD protection circuitry, perma-

nent 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!

ESD SENSITIVE DEVICE
