DESCRIPTION:
Maxwell Technologies' OP400 monolithic quad operational amplifier microcircuit features a greater than 100 krad (Si) typical total dose tolerance, depending upon space mission. Using Maxwell's radiation-hardened RAD-PAK(R) packaging technology, the OP400 has an extremely low input offset voltage no less than 150 mV with a drift of under 1.2 mV/C, guaranteed over the full military temperature range. The OP400 features low power consumption, drawing less than 725 A per amplifier. 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.
