DESCRIPTION:

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.
