ADR03WARZ-R7

Overview

The ADR03WARZ-R7 is a precision bandgap voltage reference manufactured by Analog Devices Inc. It provides a stable output voltage of 2.5 V with an initial accuracy of 0.1%. The device features a low temperature coefficient of 3 PPM/C, ensuring high stability across the operating temperature range of -40°C to +125°C. It operates from a supply voltage up to 36 V and draws a typical quiescent current of 1 mA. The component is housed in an SOIC-8 surface-mount package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Delivers a precise 2.5 V reference output with 0.1% initial accuracy
• Maintains high thermal stability with a 3 PPM/C temperature coefficient
• Supports wide input voltage ranges up to 36 V
• Qualified for automotive environments under AEC-Q100 standards

Applications

• High-resolution data acquisition systems
• Precision analog-to-digital converter references
• Automotive sensor signal conditioning circuits
• Industrial process control instrumentation

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm AEC-Q100 qualification status if automotive reliability is required. Check datasheet for derating curves at maximum operating temperatures. Ensure input voltage does not exceed the 36 V absolute maximum rating. Validate pinout compatibility with existing SOIC-8 footprints during design integration.

Selection Notes

Select this component when a 2.5 V reference is required with tight tolerance and low drift. Compare against other ADR03 variants based on package type and initial accuracy requirements. Consider the 1 mA quiescent current for power-sensitive designs. Verify that the SOIC-8 package fits the available board space. Ensure the operating temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to the ADR03 series of precision bandgap voltage references from Analog Devices. The series includes various output voltages and packages. The WARZ suffix typically denotes automotive qualification and specific packaging options. Other members may offer different accuracies or lower noise profiles depending on the specific model variant selected for the circuit design.

Replacement Considerations

ADR03WARZ is the non-reel equivalent. ADR03BUJZ offers similar performance in a TSOT-23-5 package.
