internal sample/hold function. Longer conversion times may degrade performance. See “General Conversion Guidelines” for additional explanation of maximum con-

*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.
WARNING!
ESD SENSITIVE DEVICE
CAUTION
The AD676 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 AD676
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 discharged to the destination socket before devices are removed. For further
information on ESD Precaution. Refer to Analog Devices’ ESD Prevention Manual.
