WARNING!

ESD SENSITIVE DEVICE

ESD SENSITIVITY

The AD766 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

AD766 has been classified as a Category 1 Device.

Proper ESD precautions are strongly recommended to avoid functional damage or perfor-

mance degradation. Charges as high as 4000 volts readily accumulate on the human body and

test equipment, and discharge without detection. Unused devices must be stored in conduc-

tive foam or shunts, and the foam discharged to the destination socket before devices are

removed. For further information on ESD precaution, refer to Analog Devices’ ESD

Prevention Manual.

*Stresses greater than 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 section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect device reliability.
