Maxwell Technologies’ 7545B is a 12-bit CMOS-buffered multiplying DAC with internal data latches, which features a
greater than 100 krad (Si) total dose tolerance, depending
upon space mission. The 754B features a WR pulse width of
100 ns which allows interfacing to a much wider range of fast
8-bit and 16-bit microprocessors. It is loaded by a single 12-bit
wide word under the control of the CS and WR inputs; tying
these control inputs low makes the input latches transparent
allowing unbuffered operation of the DAC. The 7545B is particularly suitable for single supply operations and applications
with wide temperature variations.
Maxwell Technologies' patented RAD-PAK® packaging technology incorporates radiation shielding in the microcircuit package. 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 50
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.
