GENERAL DESCRIPTION
The HDD-08l0 and HOD-lOtS combine state-of-the-art tech-
nology with the latest active laser trimming techniques to
achieve the world's fastest 8- and to-bit voltage output dlgital-
to-analog converters of their type.
Containing input registers and an ultra stable monolithic in-
ternal reference, the HDD-08l0 8-bit D/A converter settles to
