ADR02AUJ-R2

Overview

The ADR02AUJ-R2 is a precision voltage reference from Analog Devices, featuring a fixed 5 V output. It utilizes a bandgap architecture with an initial accuracy of 0.1% and a temperature coefficient of 3 ppm/°C. The device operates within a supply voltage range of 7 V to 36 V and draws 1 mA of quiescent current. It supports a maximum shunt current of 10 mA and functions reliably across temperatures from -40°C to +125°C. Packaged in a TSOT-23-5 surface-mount case.

Feature Summary

• Fixed 5 V output via series precision bandgap architecture
• High initial accuracy of 0.1% for precise measurement applications
• Low temperature coefficient of 3 ppm/°C ensures thermal stability
• Wide input voltage capability up to 36 V

Applications

• Precision analog-to-digital converter (ADC) references
• Data acquisition systems requiring stable voltage sources
• Industrial instrumentation signal conditioning
• Calibration equipment needing low drift

Procurement Notes

Verify the specific suffix against official documentation, as 'R2' may indicate reel packaging or a specific variant distinct from standard tape-and-reel configurations. Confirm RoHS compliance status directly with the manufacturer's latest datasheet before integration. Ensure the operating environment remains within the specified -40°C to +125°C range to maintain the guaranteed 3 ppm/°C performance characteristics.

Selection Notes

Select this component when a fixed 5 V reference is required with high accuracy and wide input voltage tolerance. The TSOT-23-5 package suits space-constrained designs. Compare against other ADR series parts if lower noise or different output voltages are needed. Verify that the 1 mA quiescent current aligns with system power budgets.

Part Context

Part of the ADR02 series of precision bandgap voltage references. Designed for applications demanding high accuracy and low temperature drift. Manufactured by Analog Devices Inc., known for high-performance signal processing components. The TSOT-23-5 package provides a compact solution for modern PCB layouts.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADR series, such as ADR02AUJZ-REEL7, ensuring identical electrical specifications. Verify package compatibility and thermal performance before substitution.
