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.

The HS 3860 includes an internal precision reference

supply, a fast output amplifier for minimum settling

time, and input registers for easier microprocessor

interface.

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.
