DESCRIPTION:
•
•
RAD-PAK® technology-hardened against natural space radi-
ation
Maxwell Technologies’ OP490 micropower quad operational
amplifier microcircuit features Maxwell’s radiation-hardened
RAD-PAK® packaging technology, the OP490 has an extremely
low input offset voltage no less than 0.5 mV with a drift of
under 5 µV/°C, guaranteed over the full military temperature
range. The OP490 features low power consumption, drawing
less than 20 µA per amplifier.
Package:
- 16 pin Rad-Pak® flat package
Low input offset voltage: 5 µV max
Low offset voltage drift
•
•
- 5 µV/°C max (over -55 to +125°C)
Low supply current (per amplifier) 20 µA max
High open-loop gain 700 V/me min.
Outstanding PSRR: 5.6 µV/V min.
•
•
•
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. This product is available with screening up to Class
S.
