® 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.

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.
