REF01AJ/883C

Overview

The REF01AJ/883C is a precision series voltage reference integrated circuit manufactured by Analog Devices Inc. It provides a fixed +10V output with high initial accuracy and low temperature drift, designed for military and aerospace applications under the MIL-PRF-38534 specification (indicated by the /883 suffix). The device operates within a wide input voltage range of 12V to 40V and features a maximum supply current of 1.4mA. It utilizes an 8-pin metal can package (MBCY8) compatible with TO-99 standards.

Feature Summary

• Provides stable +10V precision voltage reference output
• Features low temperature coefficient for thermal stability
• Includes internal trim terminals for output adjustment
• Supports temperature monitoring via dedicated terminal

Applications

• Military avionics systems requiring radiation-hardened or high-reliability components
• Aerospace instrumentation and control circuits
• High-precision data acquisition systems in harsh environments
• Calibration equipment requiring stable reference voltages

Procurement Notes

Verify that the specific lot matches the required MIL-PRF-38534 qualification level. Confirm the presence of the /883 suffix indicates military-grade screening. Check for authenticity markers on the metal can package. Ensure compatibility with existing TO-99 footprints. Request full traceability documentation upon order.

Selection Notes

Select this component when a fixed 10V reference is needed in a ruggedized metal can package. Consider it for designs requiring MIL-PRF-38534 compliance. Evaluate if the 1.4mA supply current meets power constraints. Verify that the 8-pin DIP footprint fits the PCB layout. Compare against commercial REF01 variants if military specs are not mandatory.

Part Context

The REF01 series is a legacy line of precision voltage references from Analog Devices and Maxim Integrated. While commercial versions like REF01CPZ are widely used, the /883 variant denotes a specialized military grade. This part belongs to the broader family of 10V references but is distinct due to its packaging and reliability standards intended for defense applications.

Replacement Considerations

Direct substitutes include other MIL-PRF-38534 qualified 10V references in TO-99 packages. Commercial equivalents like REF01CPZ offer similar electrical performance but lack military screening. ADR01 series devices are pin-compatible alternatives for non-military designs.
