REF02AJ/883C

Overview

The REF02AJ/883C is a high-precision series voltage reference manufactured by Analog Devices Inc., designed for military and aerospace applications. It provides a fixed 10V output with an initial accuracy of ±0.1% and a temperature coefficient of 5ppm/°C. The device operates within a supply voltage range of 11V to 36V, drawing a typical supply current of 1.4mA. It features low noise performance of 15µVp-p in the 0.1Hz to 10Hz band and supports a maximum load current of 10mA. Packaged in an 8-CERDIP format, it is qualified to MIL-STD-883 standards and functions reliably across an extended temperature range of -55°C to +125°C.

Feature Summary

• Military-grade qualification compliant with MIL-STD-883 standards
• High precision 10V fixed output with ±0.1% initial accuracy
• Low drift characteristic with 5ppm/°C temperature coefficient
• Robust ceramic dual in-line package suitable for harsh environments

Applications

• Precision data acquisition systems requiring stable references
• Aerospace instrumentation and control circuits
• High-resolution analog-to-digital converter front ends
• Military test and measurement equipment

Procurement Notes

Verify component authenticity through authorized channels due to military qualification requirements. Confirm specific lot traceability and screening levels required for your application. Check for availability as this part may be subject to long lead times or discontinuation status. Ensure packaging integrity matches the ceramic DIP specification upon receipt.

Selection Notes

Select this component when a stable 10V reference is needed for critical military or space applications. Compare against other REF02 variants based on output voltage tolerance and package type. Consider the 10mA load capability and 1.4mA quiescent current for power budgeting. Ensure the system design accommodates the minimum 11V supply requirement for proper regulation.

Part Context

This part belongs to the REF02 family of precision voltage references from Analog Devices. The /883C suffix indicates compliance with MIL-STD-883 testing and screening procedures. It serves as a radiation-hardened and vibration-resistant alternative to commercial grade references, ensuring reliability in extreme environmental conditions where standard plastic packages might fail.

Replacement Considerations

Direct replacements include other MIL-qualified versions of the REF02 series such as REF02AZ/883C if a 5V output is acceptable. Commercial equivalents like REF02HN8#PBF lack the military qualification and may not meet the same environmental specifications.
