ADOP07CQ

Overview

The ADOP07CQ is a space-qualified, ultra-low offset voltage operational amplifier manufactured by Analog Devices Inc. It features a maximum input offset voltage of 60 µV and an input bias current of 1.8 nA. The device operates on a supply voltage range of 6 V to 36 V with a typical current consumption of 3.5 mA. It has a slew rate of 0.17 V/µs and is housed in an 8-CERDIP package. The operating temperature range is specified from 0°C to 70°C.

Feature Summary

• Space-qualified die meeting Class K qualification requirements for high reliability applications
• Ultra-low input offset voltage achieved through wafer-stage trimming
• Low input bias current suitable for precision signal conditioning

Applications

• Space instrumentation systems requiring radiation-hardened or qualified components
• Precision sensor signal amplification in aerospace environments
• High-accuracy data acquisition systems for satellite payloads

Procurement Notes

Verify the specific revision level and lot traceability when ordering space-qualified components. Confirm that the 8-CERDIP package matches your board layout constraints. Ensure the supplier provides documentation confirming Class K qualification status as required by your mission specifications. Check for any special handling instructions associated with ceramic DIP packages.

Selection Notes

Select this component when mission-critical reliability and low offset are prioritized over speed. The 0.17 V/µs slew rate limits bandwidth compared to general-purpose op-amps. Consider the 8-CERDIP package size if space is not a primary constraint. Verify that the 0°C to 70°C commercial temperature range meets your environmental requirements, as some space variants may offer wider ranges.

Part Context

The ADOP07CQ belongs to the OP07 family of precision operational amplifiers. While standard OP07 devices are widely used in industrial applications, the CQ suffix denotes a version qualified for space environments. This variant maintains the core electrical characteristics of the OP07 but undergoes additional screening and qualification processes to ensure performance in harsh conditions.

Replacement Considerations

Direct substitutes include other space-qualified versions of the OP07 family. Verify pin compatibility and electrical parameters against the ADOP07CQ datasheet. Generic OP07 replacements lack the necessary space qualification and should not be used without re-qualification.
