Stresses above those listed under “Absolute Maximum Ratings”

may cause permanent damage to the device. This is a stress

rating only and functional operation at or above this specifica-

tion is not implied. Exposure to above maximum rating

conditions for extended periods may affect device reliability.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on

the human body and test equipment and can discharge without detection. Although this product features

proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy

electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance

degradation or loss of functionality.

The Sine-Wave Digital Code Is Set at 1000 000 0000. Scale: Reference Input Is

5 V/DIV (Thin Trace). Feedthrough Output Is 5 mV/DIV. Time: 5 ms/DIV (Top

Photo), 500 µs/DIV (Bottom Photo).

MIL-STD-883

The rigors of the military and aerospace environment, temp-

erature extremes, humidity, mechanical stress, etc., demand the

utmost in electronic circuits. The AD394, with the inherent

reliability of an integrated circuit construction, was designed

with these applications in mind. The hermetically-sealed, low

profile DIP package takes up a fraction of the space required by

equivalent modular designs and protects the chips from

hazardous environments. To further insure reliability, the

AD394 is fully compliant to MIL-STD-833 Class B, Method

5008.
