REF02DSA+

Overview

The REF02DSA+ is a precision voltage reference integrated circuit manufactured by Analog Devices Inc. (Maxim Integrated). It utilizes a series topology with a buried Zener architecture to deliver a fixed nominal output voltage of 5V. The device features an initial accuracy tolerance of ±1.0% and operates within a supply voltage range of 7.3V to 33V. Designed for through-hole installation, it is housed in an 8-pin DIP package. The component supports an operating temperature range from -40°C to +85°C, ensuring stability across industrial environments.

Feature Summary

• Series topology utilizing buried Zener technology for high precision
• Fixed 5V output with ±1.0% initial accuracy
• Wide input voltage capability up to 33V
• Industrial temperature range operation

Applications

• Precision analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage sources
• High-accuracy measurement instrumentation
• Calibration equipment requiring stable DC references

Procurement Notes

Verify the specific suffix 'DSA+' against official manufacturer documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status via current datasheets as manufacturing practices may evolve. Ensure the selected variant matches the required thermal performance for the intended application environment.

Selection Notes

Select this component when a fixed 5V reference with ±1.0% accuracy is required. Consider the 8-pin DIP package for through-hole PCB designs. Evaluate the 7.3V minimum input requirement against available system rails. Compare noise specifications and temperature coefficients if higher precision than standard series references is needed.

Part Context

The REF02 series represents Maxim Integrated's line of precision voltage references. These devices are designed to provide stable reference voltages for data acquisition systems. The REF02DSA+ specifically denotes the 5V version in a DIP-8 package, serving as a fundamental building block for analog signal conditioning circuits.

Replacement Considerations

Consult official cross-reference guides for direct replacements. Verify that any substitute maintains the same 5V output, ±1.0% accuracy, and 8-pin DIP footprint. Ensure thermal and electrical characteristics match the original design requirements.
