ADR02BRZ

Overview

The ADR02BRZ is a precision voltage reference IC from Analog Devices, providing a fixed 5.0 V output with ±0.1% initial accuracy and a temperature coefficient of 3 ppm/°C. It operates within an input voltage range of 12.0 V to 36.0 V, delivering up to 10 mA of output current while consuming only 800 µA of supply current. The device features ultra-low noise performance at 10 µV peak-to-peak (0.1 Hz to 10 Hz) and requires no external capacitors for stability. Packaged in an 8-pin SOIC format, it supports extended industrial temperatures from -40°C to +125°C.

Feature Summary

• Pin-compatible replacement for industry-standard REF02 devices in 8-pin SOIC packages
• Integrated buffer circuit eliminates the need for external compensation capacitors
• Includes dedicated TRIM pin for precise output voltage adjustment
• Features TEMP pin enabling internal die temperature monitoring

Applications

• High-resolution data acquisition systems
• Precision analog-to-digital converter biasing
• Industrial process control instrumentation
• Battery monitoring circuits requiring stable references

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure the procurement channel provides valid traceability for industrial-grade components. Confirm RoHS compliance status through current datasheets before integration into regulated designs.

Selection Notes

Select this component when system design requires a compact, low-noise reference that directly replaces legacy REF02 hardware without PCB layout changes. The integrated buffer simplifies design complexity by removing external stabilization requirements. Verify that the 12 V minimum input voltage aligns with available power rails.

Part Context

This part belongs to the ADR0x series of ultra-compact precision voltage references. The series includes variants offering 10 V, 2.5 V, and 3.0 V outputs. All members share similar architectural benefits, including small footprint options and wide operating voltage ranges suitable for space-constrained applications.

Replacement Considerations

Officially documented pin-compatible substitutes include the REF02JN and REF02CP. These legacy parts match the 8-pin SOIC footprint but may lack the integrated buffer or temperature monitoring features found in the ADR02.
