Description

Maxwell Technologies' 8143 is a 12-bit serial-input daisy-chain CMOS digital-to-analog converter (DAC) that features serial data input and buffered serial data output and a greater than 50 krad (Si) total dose tolerance, dependent upon space mis-sion. 8143 was designed for multiple serial DAC systems, where serially daisy-chaining one DAC after another is greatly simpli-fied. The 8143 also minimizes address decoding lines enabling simpler logic interfacing. It allows three-wire interface for any number of DACs: one data line, one CLK line and one load line. Serial data in the input register (MSB first) is sequentially clocked out to the SRO pin as the new data word (MSB first) is simultaneously clocked in from the SRI pin. The strobe inputs are used to clock in/out data on the rising or fall-ing (user selected) strobe edges (STB₁ , STB₂ , STB₃ , STB₄ ).When the shift register's data has been updated, the new data word is transferred to the DAC register with use of LO1 and LD2 inputs.

Maxwell Technologies' patented RAD-PAK^(R) packaging technol-ogy incorporates radiation shielding in the microcircuit pack-age.  8143 eliminates the need for box shielding while providing the required radiation shielding for a lifetime in orbit or space mission.  In a GEO orbit, RAD-PAK provides greater than 50 krad (Si) radiation dose tolerance. 8143 is available with screening up to Class S.
