ation

• 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

Maxwell Technologies’ OP490 micropower quad operational

amplifier microcircuit features Maxwell’s radiation-hardened

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.

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.
