H S3160 D ata Converter Line Monolithic 16-Bit MD AC FEATURES • M onolithic CM OS circuit • Linearity ±0.003% • Linearity TC 1 ppm/ ºC max. • Latch-up protected • Small size: 22-pin ceramic DIP • Commercial and M IL-STD-883 Rev. C processing • Single power supply: + 15V DC • Low power: 30 mW 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.
