OP490RPFS

Low Voltage Micropower Quad Operational Amplifier OP490 Logic Diagram Memory FEATURES: • RAD-PAK® technology-hardened against natural space radiation • 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 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. Maxwell Technologies' patented RAD-PAK packaging technology 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.
