ADR02ARZ

Overview

The ADR02ARZ is an ultracompact precision voltage reference from Analog Devices, featuring a bandgap architecture with a fixed 5.0 V output. It delivers high accuracy with an initial tolerance of ±0.1% and a temperature coefficient of 10 ppm/°C across the -40°C to +125°C industrial range. The device operates on a supply voltage between 7.0 V and 36.0 V, consuming only 1 mA of quiescent current while providing up to 10 mA of output current without external capacitors. Key electrical parameters include line regulation of 30 ppm/V, load regulation of 70 ppm/mA, and low noise of 10 µV p-p in the 0.1 Hz to 10 Hz bandwidth.

Feature Summary

• Integrates an internal buffer amplifier and simple resistor network for stable operation
• Provides dedicated TEMP pin for external temperature sensing capabilities
• Includes TRIM pin for precise manual adjustment of the output voltage
• Delivers high output current capability without requiring external compensation capacitors

Applications

• Precision data acquisition systems
• High-resolution analog-to-digital converters
• Industrial process control instrumentation
• Automatic battery monitoring circuits

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and reel specifications. Ensure the operating environment remains within the specified -40°C to +125°C thermal limits. Confirm that input voltage stays between 7.0 V and 36.0 V to maintain rated performance. Check RoHS compliance status if required by your manufacturing standards. Validate pinout compatibility during PCB layout integration.

Selection Notes

Select this component when a fixed 5.0 V reference with ±0.1% initial accuracy is required. Choose this part for applications needing low power consumption under 1 mA. Consider this device for designs requiring a compact SOIC-8 footprint. Opt for this reference if external trimming or temperature sensing features are necessary. Evaluate this option for systems demanding low noise performance below 10 µV p-p.

Part Context

The ADR02ARZ belongs to the ADR02 series of ultracompact precision voltage references manufactured by Analog Devices. This series includes variants with different output voltages such as 2.5 V, 3.0 V, and 10.0 V. The family shares common architectural features including bandgap technology and integrated buffering. These devices are designed for applications requiring high stability and low drift over wide temperature ranges.

Replacement Considerations

ADR02ARZ-REEL serves as the reel-packaged equivalent of the tube version.
