ADR292FR-REEL

Overview

The ADR292FR-REEL is a low noise, micropower precision voltage reference utilizing XFET architecture. It provides a fixed output of 4.096 V with an initial accuracy of ±0.10% and a maximum temperature coefficient of 15 ppm/°C. The device operates from a supply range of 4.4 V to 15 V, drawing a typical quiescent current of 12 μA at 25°C. It features a low noise output of 12 μV p-p (0.1 Hz to 10 Hz) and supports a maximum load current of 5 mA. The component is housed in an 8-lead SOIC package and functions within an extended industrial temperature range of −40°C to +125°C.

Procurement Notes

Verify the specific suffix REEL7 against the ordering guide to confirm the reel quantity matches project requirements. Ensure the FRZ designation corresponds to the required F grade specifications. Confirm the SOIC package type aligns with PCB footprint constraints. Validate that the operating voltage range meets system input conditions.

Selection Notes

Select this part when a stable 4.096 V reference is needed with low power consumption. The F grade offers a balance between accuracy and cost. Consider thermal dissipation if operating near maximum input voltages. Verify compatibility with existing REF02/REF19x footprints if replacing legacy components.

Part Context

The ADR292FR-REEL belongs to the ADR291/ADR292 family of precision voltage references manufactured by Analog Devices. This series employs the XFET technology to achieve superior performance compared to traditional band gap or buried Zener references. The family includes variants with different output voltages, accuracies, and packaging options to suit diverse electronic design needs.

Replacement Considerations

The datasheet indicates pin-compatibility with REF02 and REF19x series devices. Designers replacing these legacy parts should verify electrical parameter alignment, particularly regarding noise and temperature coefficients.
