Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and reel configuration. Ensure the ordering part number matches the required tolerance and temperature grade specifications. Cross-reference the manufacturer's latest datasheet revision to validate pinout compatibility with existing REF02 footprints before finalizing procurement orders.

Selection Notes

Select this component when a stable 5.0 V reference is required in compact surface-mount layouts. It serves as a direct substitute for legacy REF02 parts, simplifying board redesigns. Consider its 10 mA output capability for driving moderate loads while maintaining tight accuracy constraints in sensitive measurement environments.

Part Context

This part belongs to the ADR0x series of ultracompact voltage references, which includes variants offering 10.0 V, 2.5 V, and 3.0 V outputs. The series is characterized by low power consumption and wide operating ranges. The ADR02 specifically targets applications needing precise 5.0 V regulation in small form factors.

Replacement Considerations

The ADR02ARZ-REEL is documented as a drop-in replacement for the industry-standard REF02. Verify pinout compatibility and thermal characteristics when substituting into existing REF02 designs.
