REF01AH

Overview

The REF01AH is a precision bandgap voltage reference providing a fixed 10V output. It features an initial accuracy of ±0.3% and a typical temperature coefficient of 5ppm/°C. The device operates within an extended temperature range of -55°C to 125°C. Electrical specifications include a maximum quiescent supply current of 1.4mA, a load current capability of 10mA, and a short-circuit current of 25mA. Input voltage ranges from 12V to 40V. Output noise is specified at 20µVP-P in the 0.1Hz to 10Hz bandwidth.

Feature Summary

• Provides stable 10V output with low drift characteristics suitable for precision applications
• Features high line rejection and low power consumption
• Includes adjustable output voltage range via external potentiometer
• Capable of 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 AH indicates the TO-5 metal can package and extended temperature range. Confirm lead-free status if required by assembly processes. Check for obsolete status or alternative sourcing options as Linear Technology was acquired by Analog Devices. Ensure pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component when extended temperature operation down to -55°C is required alongside precision voltage referencing. Compare against REF01EN8 for plastic DIP packages if thermal constraints allow lower operating limits. Consider the REF02 series if a 5V output or temperature sensing capability is needed instead of the fixed 10V provided by the REF01 variant.

Part Context

This part belongs to the REF-01/REF-02 family of precision voltage references originally manufactured by Linear Technology Corporation. The REF-01 specifically provides a 10V output, while the REF-02 provides 5V. These devices are designed for applications requiring low drift and moderate accuracy. The manufacturer has since become part of Analog Devices Inc., which continues to support the product line.
