DESCRIPTION:
Maxwell Technologies 139 consisting of four independent precision voltage comparators, features a greater than 100 krad (Si) total dose tolerance, depending upon space mission. Using Maxwell Technologies radiation- hardened Rad-Pak® packaging technology, the 139 has an offset voltage specification as low as 2 mV max for all four comparators.
