Low Power, W ide
Temperature Range D ACs
FEATURES
• 10- and 12-bit models
• V ery low power: less than 300 mW
• W ide operating temperature range:
• M IL-STD-883 Rev. C, Level B or commercial
• 18 pin hermetic package
DESCRIPTION
This Series is specifically designed and tested for low
power operation. The models feature low total
power dissipation of less than 300 mW . Each unit
incorporates a pretrimmed output amplifier and a
low power internal reference.
The DA C347 Series are high performance, general
purpose, digital to analog converters utilizing
matched CM OS current switches and ultra stable thin-
film nichrome resistor networks. A ll DA C347 Series
models provide optimum stability in performance
over the full –55ºC to + 125ºC temperature range.

Unipolar models use complementary binary coding
and bipolar models use complementary offset binary
coding. Each DA C347 Series converter comes
packaged in a hermetically sealed 18-pin package,
ideal for applications where maximum performance
in minimum space is required.
