*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 indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
ESD SENSITIVITY
The AD678 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 AD678 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 equipment
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.
