ADR03ARZ

Overview

The ADR03ARZ is a precision series voltage reference from Analog Devices, housed in an 8-SOIC surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.2%. The device operates within an input voltage range of 4.5 V to 36 V and supports a maximum shunt current of 10 mA. It features a temperature coefficient of 3 PPM/°C and consumes 1 mA of supply current. The component functions reliably across a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Delivers high-precision voltage regulation with low temperature drift characteristics suitable for demanding measurement applications.
• Integrates a bandgap reference core optimized for stability and minimal noise performance over the specified operating range.
• Supports flexible system integration through a standard surface-mount package compatible with automated assembly processes.

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• High-resolution instrumentation amplifier biasing

Procurement Notes

Verify the specific suffix 'ARZ' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm that the required output voltage and current capabilities align with the target circuit design before procurement. Check for any product change notifications regarding manufacturing site updates or material substitutions.

Selection Notes

Select this component when a stable 2.5 V reference is required with moderate accuracy specifications. Consider the 3 PPM/°C temperature coefficient for thermal stability requirements. Ensure the power supply voltage remains within the 4.5 V to 36 V operational window to maintain regulation. Evaluate the 1 mA quiescent current consumption against system power budgets.

Part Context

The ADR03ARZ belongs to the ADR03 family of precision voltage references manufactured by Analog Devices. This series is designed for applications requiring reliable voltage standards in industrial and scientific equipment. The part utilizes a bandgap architecture to achieve its specified performance metrics across the extended industrial temperature range.

Replacement Considerations

Consult official documentation for qualified substitutes such as the ADR03BRZ for tighter tolerance requirements or other members of the ADR01/ADR02/ADR03 family depending on voltage and accuracy needs.
