ADR02CRZ

Overview

The ADR02CRZ is a precision voltage reference from Analog Devices, delivering a fixed 5.0 V output with an initial accuracy of ±0.1%. It operates within a wide input voltage range of 12.0 V to 36.0 V and provides a maximum output current of 10 mA. The device features a low noise level of 10 μV peak-to-peak (0.1 Hz to 10.0 Hz) and requires no external capacitors for stability. It supports an extended industrial temperature range from -40°C to +125°C. The SOIC-8 package exhibits a temperature coefficient of 3 ppm/°C.

Feature Summary

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

Applications

• High-resolution analog-to-digital converters
• Precision digital-to-analog converters
• Industrial process control systems
• Portable battery-powered instrumentation

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact performance grades and packaging details. Confirm availability status as certain variants may be discontinued or subject to change. Ensure the selected package matches the required PCB footprint and thermal management specifications for the target application environment.

Selection Notes

Select this component when a stable 5.0 V reference is required in space-constrained designs utilizing SOIC-8 footprints. It serves as a direct drop-in upgrade for legacy REF02 implementations while offering improved temperature stability and integrated diagnostic capabilities via the TEMP pin. Consider the 3 ppm/°C drift rate for high-precision applications over wide temperature ranges.

Part Context

The ADR02CRZ belongs to the ADR0x series of ultra-compact precision bandgap references. This family includes variants with different output voltages such as 2.5 V, 3.0 V, and 10.0 V. The series is designed for general-purpose and space-limited applications, offering a balance of low power consumption, high accuracy, and robust performance across industrial temperature extremes.

Replacement Considerations

The ADR02CRZ is officially documented as a pin-compatible substitute for the REF02 in the 8-pin SOIC package. Designers upgrading from REF02 should verify system-level compatibility, as electrical characteristics differ despite identical pinouts.
