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® 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 µ A per amplifier.
