DESCRIPTION
The HS 3860 is a 12-Bit digital-to-analog converter
packaged in a hermetically sealed 24-pin double-
width, dual-in-line package.
The D/A is constructed using hybrid microcircuit
technology and includes a precision thin-film
network, laser-trimmed to produce a high linearity,
high accuracy converter, stable over a wide
temperature range. Errors in linearity and accuracy
are specified at room temperature as well as
operating temperature extremes for both military
and commercial products.

D ata Converter Line
The HS 3860 includes an internal precision reference
supply, a fast output amplifier for minimum settling
time, and input registers for easier microprocessor
in t e r f a ce .
M IL-STD-883 Rev. C, Level B screening and processing
is available in the “ B” grade device. Operating
temperature range for the HS 3860B is – 55ºC to
+125ºC.
