NOTES

*Stresses above those listed under “Absolute Maximum Ratings” may cause

permanent damage to the device. This is a stress rating only and functional

operation of the device at these or any other conditions above those indicated in

the operational sections of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect device reliability.

1The AD679 is not designed to operate from ±15 V supplies.

CAUTION

The AD679 features input protection circuitry consisting of large “distributed” diodes and

polysilicon series resistors to dissipate both high energy discharges (Human Body Model) and fast,

low energy pulses (Charged Device Model). Per Method 3015.2 of MIL-STD-883C, the AD679 has

been classified as a Category 1 device.

Proper ESD precautions are strongly recommended to avoid functional damage or performance

degradation. Charges as high as 4000 volts readily accumulate on the human body and test equip-

ment and discharge without detection. Unused devices must be stored in conductive foam or shunts,

and the foam should be discharged to the destination socket before devices are removed. For further

information on ESD precautions, refer to Analog Devices’ ESD Prevention Manual.
