Maxwell Technologies' 7846A 16-Bit DAC converter microcir-cuit features a greater than 100 krad (Si) total dose tolerance,depending upon space mission. The 7846A has VREF+ and VREF- reference inputs and an on-chip output amplifier which gives the option of unipolar or bipolar output. The 7846A uses
a segmented architecture. The 4 MSBs of the 7846A in the DAC latch select one of the segments in a 16-resistor string. Both taps of the segment are buffered by amplifiers and fed to a 12-bit DAC, which provides a further 12 bits of resolution. This archi-tecture ensures 16-bit monotonicity. Excellent integral linearity results from tight matching between the input offset voltages of the two buffer amplifiers. In addition to the excellent accu-racy specifications, the 7846A also offers a comprehensive microprocessor interface. There are 16 data I/O pins, plus control lines (CS</a>, R/W</a>, LDAC</a> and CLR</a>). R/W</a> and CS</a> have readback function which allows writing to and reading from the I/O latch.
Maxwell Technologies' patented RAD-PAK® packaging technol-ogy incorporates radiation shielding in the microcircuit pack-age. It 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 100 krad (Si) radiation dose tolerance. This product is available with screening up to Class S.
