OP400 Quad Low-Offset, Low-Power Operational Amplifier v+ BIAS OUT VOL TAGE LIMITING NETWORK +IN -IN v- Logic Diagram DESCRIPTION: • RAD-PAK® technology-hardened against natural space • radiation • Total dose hardness: - > 100 krad (Si), depending upon space mission • Package: - 16 pin Rad-Pak® flat package • Low input offset voltage 150µ V max • Low offset voltage drift - +1.2µ V/°C max (over -55 to +125°C) • Low supply current (per amplifier) 725 µ A max • High open-loop gain 5000V/mV min • Input bias current 3 nA Max • Low noise voltage density 11 nV per (Hz)½ at 1 kHz • Stable with large capacitive loads 10 nF typ Maxwell Technologies’ OP400 monolithic quad operational amplifier microcircuit features a greater than 100 krad (Si) typical total dose tolerance, depending upon space mission. Using Maxwell’s radiation-hardened RAD-PAK® packaging technology, the OP400 has an extremely low input offset voltage no less than 150 mV with a drift of under 1.2 mV/°C, guaranteed over the full military temperature range. The OP400 features low power consumption, drawing less than 725 µ A 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. In a GEO orbit, RAD-PAK provides greater than 100 krad (Si) radiation dose tolerance. This product is available with screening up to Class S. 09.12.02 REV 5 (858) 503-3300 - Fax: (858) 503-3301 - www.maxwell.com All data sheets are subject to change without notice 1 ©2001 Maxwell Technologies All rights reserved.
