DESCRIPTION
The HS3160 is a 16-bit CM OS multiplying D/A
converter integrated in a single monolithic chip. It
represents a major advance in the field of monolithic
converter technology, extending resolution to 16 bits
and with linearity to 14 bits and 0.003%. The HS3160
accepts A C or DC reference voltages, multiplies in all
four quadrants, has latch-up protection, and is
packaged in a hermetic 22-pin DIP. Outstanding
features of the HS3160 include:
14-Bit Linearity — HS3160 offers a 0.003% integral
linearity and a 0.003% differential linearity and is
monotonic over the entire specified operating
temperature range. The excellent differential
linearity is achieved by using a unique bit decoding
technique. The transfer function is actually divided
into 16 segments (determined by bits 1 to 4), each
consisting of 4,096 discrete voltage levels (determined

by bits 5 to 16). Bits 1 to 4 are digitally decoded into
15 control signals, driving 15 equal current sources,
rather than 4 binarily weighted sources; thus
reducing the matching accuracy requirement on the
resistors and CM OS switches.
M onolithic Construction — HS3160 is a single chip
CM OS circuit using advanced design and
manufacturing techniques.
Processing — The HS3160 is offered in two versions.
The -C version is commercially processed for
applications in the 0ºC to 70ºC range. The -B version
operates in the -55ºC to +125ºC temperature range
and is processed and screened to the requirements
of M IL-M -38510 and M IL-STD-883C.
