*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 indi-
cated in the operational sections of this specification is not implied. Expo-
sure to absolute maximum rating conditions for extended periods may affect
device reliability.

ESD SENSITIVITY
The AD1678 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 AD1678
has been classified as a Category A 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.
