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

• High open-loop gain 700 V/me min.

• Outstanding PSRR: 5.6 µV/V min.

DESCRIPTION:

Maxwell Technologies’ OP490 micropower quad operational
amplifier microcircuit features Maxwell’s radiation-hardened
R

AD-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.

Maxwell Technologies' patented R
ogy incorporates radiation shielding in the microcircuit pack­age. 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.
