DESCRIPTION:
• RAD-PAK® technology-hardened against natural space
• radiation
• Total dose hardness:
- > 100 krad (Si), depending upon space mission
• Package:
- 16 pin Rad-Pak® flat package
• Low input offset voltage 150µV max
• Low offset voltage drift
Maxwell Technologies’ OP400 monolithic quad operational
amplifier microcircuit features a greater than 100 krad (Si) typ-
ical total dose tolerance, depending upon space mission.
Using Maxwell’s radiation-hardened RAD-PAK® packaging
technology, the OP400 has an extremely low input offset volt-
age no less than 150 mV with a drift of under 1.2 mV/°C, guar-
anteed over the full military temperature range. The OP400
features low power consumption, drawing less than 725 µA
per amplifier.
- +1.2µV/°C max (over -55 to +125°C)
• Low supply current (per amplifier) 725 µA max
• High open-loop gain 5000V/mV min
• Input bias current 3 nA Max
Maxwell Technologies' patented RAD-PAK packaging technol-
ogy incorporates radiation shielding in the microcircuit pack-
age. 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.
