.
2. The digital control inputs are Zener-protected; however,
permanent damage may occur on unprotected units from
high energy electrostatic fields. Keep units in conductive
foam at all times until ready to use.
3. Do not insert this device into powered sockets; remove
power before insertion or removal.
4. Use proper antistatic handling procedures.
5. Devices can suffer permanent damage and/or reliability deg-
radation if stressed above the limits listed under Absolute
Maximum Ratings for extended periods. This is a stress rat-
ing only and functional operation at or above this specifica-
tion is not implied.

NOTES
1
Burn-in is available on commercial and industrial temperature range parts in cerdip, plastic DIP, and TO-can packages.
2
For devices processed in total compliance to MIL-STD-883, add/883 after part number. Consult factory for 883 data sheet.
3
For availability and burn-in information on SO and PLCC packages, contact your local sales office.
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 the DAC8248 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.
