Maxwell Technologies’ 7545A 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 7545A features a WR pulse width of 100 ns which allows interfacing to a much wider range of fast 8-bit and 16-bit microprocessors.
The 7545A 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 7545A is particularly suitable for single supply operations and applications with wide temperature variations.
About RAD-PAK® Technology
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 100 krad (Si) radiation dose tolerance. This product is available with screening up to Class S.
