REF01HSA-T

Overview

The REF01HSA-T is a series voltage reference integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed 10V output with an initial accuracy of ±0.5%. The device operates within an input voltage range of 13V to 33V and draws a supply current of 1.4mA. It features a low temperature coefficient of 25ppm/°C and exhibits a noise level of 20µVp-p in the 0.1Hz to 10Hz frequency band. Packaged in an 8-SOIC surface-mount format, it supports operation from 0°C to +70°C.

Feature Summary

• Provides a stable fixed 10V output via series regulation architecture
• Maintains precision with a low temperature coefficient of 25ppm/°C
• Delivers low noise performance suitable for sensitive analog circuits

Applications

• Precision analog signal conditioning interfaces
• High-resolution data acquisition systems
• Calibration reference sources for measurement equipment

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm tape-and-reel packaging configuration. Ensure compatibility with standard 8-SOIC footprint requirements during PCB layout. Confirm that the operating environment remains within the specified commercial temperature range and input voltage limits to maintain rated accuracy.

Selection Notes

Select this component when a fixed 10V reference is required with moderate precision and low noise characteristics. Consider the 8-SOIC package constraints and the minimum 13V input requirement. Evaluate thermal management needs relative to the 1.4mA supply current and ambient operating conditions.

Part Context

This part belongs to the REF01 family of series voltage references designed for general-purpose precision applications. It serves as a stable voltage source for analog circuits requiring reliable reference potentials without the complexity of adjustable regulators or higher-cost ultra-low drift alternatives.

Replacement Considerations

Consult official datasheets for pin-compatible alternatives within the same series. Verify electrical parameter equivalence before substitution.
