REF01AJ

Overview

The REF01AJ is a three-terminal precision voltage reference manufactured by Analog Devices Inc. It provides a fixed nominal output voltage of 10 V using bipolar technology. The device is housed in an MBCY8 metal can package, specifically the TO-99 form factor with eight pins. It operates within an extended temperature range from -55 °C to +125 °C and meets MILITARY temperature grade standards. Key electrical specifications include a maximum voltage temperature coefficient of 8.5 ppm/°C and a tin/lead (Sn/Pb) terminal finish. The component is designed for high-reliability applications requiring stable DC voltage references.

Feature Summary

• Provides a stable 10 V fixed output via bipolar circuitry
• Constructed in a hermetic metal can package for environmental protection
• Qualified for military-grade operational temperatures

Applications

• High-reliability aerospace instrumentation
• Defense system signal conditioning
• Precision measurement equipment requiring strict thermal stability

Procurement Notes

Verify that the specific order includes the /883 suffix or equivalent qualification designation if military compliance is required, as standard commercial variants may differ in screening levels. Confirm the package type matches the MBCY8 specification and ensure the terminal finish aligns with soldering process requirements. Cross-reference the manufacturer's latest datasheet to confirm current production status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a 10 V reference with low temperature drift is necessary for harsh environments. The bipolar technology offers robust performance compared to CMOS alternatives in high-noise settings. Ensure the input voltage exceeds the minimum dropout requirement for the specific load conditions. Consider the through-hole mounting style of the metal can package during PCB layout design to accommodate the physical dimensions of the TO-99 housing.

Part Context

This part belongs to the REF01 family of precision voltage references from Analog Devices. The family includes various output voltages and packages, but the AJ variant specifically targets the 10 V output with military-grade reliability. It serves as a foundational reference element in analog signal chains where long-term stability and low noise are critical for maintaining system accuracy over time.
