NOTES
1Burn-in is available on commercial and industrial temperature range parts in cerdip, plastic DIP, and TO-can packages.
2For devices processed in total compliance to MIL-STD-883, add/883 after part number. Consult factory for 883 data sheet.
3For availability and burn-in information on SO and PLCC packages, contact your local sales office.
(continued from page 1)
operates on a single supply from +5 V to +15 V, and it dissi-
pates less than 0.5 mW at +5 V (using zero or VDD logic levels).
The device is packaged in a space-saving 0.3", 24-pin DIP.
The DAC8248 is manufactured with PMI’s highly stable thin-
film resistors on an advanced oxide-isolated, silicon-gate,
CMOS technology. PMI’s improved latch-up resistant design
eliminates the need for external protective Schottky diodes.

JA specified for worst case mounting conditions, i.e.,
JA is specified for device in
socket for cerdip and P-DIP packages; JA is specified for device soldered to printed
circuit board for SOL package.
CAUTION
1. Do not apply voltages higher than VDD or less than GND
potential on any terminal except VREF and RFB.
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.
WARNING!
ESD SENSITIVE DEVICE
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.
