ADOP07EQ

Overview

The ADOP07EQ is a space-qualified operational amplifier manufactured by Analog Devices Inc. It utilizes voltage-feedback architecture and is designed for high-reliability applications in harsh environments. The component features an extremely low average bias current, specified at a maximum of 0.004 uA. This device is part of the OP07 series adapted for space qualification standards, ensuring robust performance where precision and stability are critical.

Feature Summary

• Space-qualified design meeting Class K die qualification requirements
• Voltage-feedback operational amplifier architecture
• Ultra-low input bias current for high-impedance signal integrity

Applications

• Spaceborne instrumentation systems
• High-precision sensor signal conditioning
• Radiation-hardened data acquisition circuits

Procurement Notes

Verify the specific revision level and lot traceability documentation when sourcing this discontinued or space-grade component. Ensure that the supplier provides evidence of adherence to Analog Devices' space qualification protocols. Confirm that the package type matches the intended board layout constraints, as space-qualified variants may have distinct mechanical specifications compared to commercial equivalents.

Selection Notes

Select the ADOP07EQ only when radiation tolerance and long-term reliability in vacuum environments are mandatory. Compare its ultra-low bias current against standard OP07 variants if noise performance in high-impedance circuits is the primary design constraint. Evaluate thermal management requirements specific to space applications rather than terrestrial ambient conditions.

Part Context

This component belongs to the OP07 family of precision operational amplifiers, specifically engineered for Analog Devices' space-qualified product line. It shares the foundational electrical characteristics of the commercial OP07 but undergoes rigorous screening and qualification processes to meet aerospace standards. The 'EQ' suffix typically denotes the specific space-qualified package and processing variant.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Due to the specialized space-qualification status, direct pin-for-pin replacements must be verified against specific mission radiation tolerance requirements.
