REF01EH

Overview

The REF01EH is a precision voltage reference from the REF-01/REF-02 series, manufactured by Analog Devices Inc. It provides a fixed 10V output with an initial accuracy of ±0.3%. The device features a typical temperature coefficient of 5ppm/°C and operates within a commercial temperature range of 0°C to 70°C. It utilizes an 8-lead TO-5 metal can package (H Package). Key electrical specifications include a maximum input voltage of 40V, a quiescent supply current of 1.4mA maximum, and a load current capability of 20mA. The part is designed for applications requiring low drift and moderate accuracy.

Feature Summary

• Provides stable 10V bandgap reference output
• Features low temperature drift characteristics
• Includes high line rejection capabilities
• Supports indefinite short-circuit duration to ground

Applications

• A/D and D/A converters
• Precision regulators
• Constant current sources
• Bridge excitation circuits

Procurement Notes

Verify the specific suffix EH indicates the 0°C to 70°C operating range and TO-5 metal can package configuration. Confirm lead-free finish status and RoHS compliance details against the latest manufacturer documentation. Ensure the ordering information matches the required pinout and thermal characteristics for the target application environment.

Selection Notes

Select this component when a fixed 10V reference with ±0.3% accuracy is required in a hermetic metal can package. Consider the REF01EH over plastic packages if environmental sealing or specific military/aerospace form factors are necessary. Evaluate the 5ppm/°C typical drift against system stability requirements compared to higher precision alternatives like the LT1019.

Part Context

The REF01EH belongs to the REF-01/REF-02 family of precision voltage references originally developed by Linear Technology Corporation, now part of Analog Devices Inc. This series is known for providing stable bandgap references with low power consumption. The REF-01 variant specifically delivers a 10V output, distinguishing it from the 5V REF-02 model which also includes a temperature output pin.

Replacement Considerations

The REF01EN8#PBF is listed as a direct replacement option in distributor databases.
