REF02HSZ

Overview

The REF02HSZ is a precision voltage reference IC from Analog Devices Inc., providing a fixed 5V output with ±0.5% initial accuracy. It operates within an extended temperature range of -40°C to +85°C and accepts input voltages between 8V and 36V. The device draws a typical supply current of 1.4mA and delivers up to 10mA output current. It features a low noise profile of 15µVp-p in the 0.1Hz to 10Hz band and a temperature coefficient of 25ppm/°C. The component is housed in an 8-pin plastic DIP package.

Feature Summary

• Provides stable, fixed 5V reference output suitable for high-precision analog circuits
• Features low noise performance for sensitive signal processing applications
• Operates reliably across wide industrial temperature ranges

Applications

• Precision data acquisition systems
• Analog-to-digital converter (ADC) reference sources
• Calibration equipment requiring stable voltage standards

Procurement Notes

Verify the specific suffix HSZ against the official Analog Devices datasheet to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for 8-pin DIP configurations. Confirm RoHS compliance status for your region's regulatory requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 5V output is required with tight initial tolerance and low drift characteristics. Consider the 1.4mA quiescent current and 10mA load capability against system power budgets. Evaluate the 25ppm/°C temperature coefficient against environmental operating conditions to ensure long-term stability meets design specifications.

Part Context

The REF02 series represents a family of three-terminal precision voltage references designed by Analog Devices. These devices are engineered for applications demanding high accuracy and stability over varying temperatures and loads. The REF02HSZ specifically denotes the 5V variant with ±0.5% accuracy in a standard plastic DIP package, serving as a foundational reference element in mixed-signal designs.

Replacement Considerations

Direct substitutes include other REF02 variants with different accuracies or packages, such as REF02HPZ or REF02CSZ, provided pinout and electrical parameters align with the design requirements.
