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.
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.
