ADR293GRU-REEL7

Overview

The ADR293GRU-REEL7 is a low noise, micropower precision voltage reference providing a fixed 5.0 V output. It utilizes XFET architecture to achieve high stability and low thermal hysteresis. The device operates from a supply range of 6.0 V to 15 V with a maximum quiescent current of 15 μA. It supports an output current of up to 5 mA and maintains performance across an extended temperature range of −40°C to +125°C.

Feature Summary

• Utilizes XFET architecture for ultralinear temperature drift and low thermal hysteresis
• Provides stable 5.0 V output with high initial accuracy grades
• Features low noise characteristics suitable for sensitive analog circuits
• Capable of sourcing load currents up to 5 mA

Applications

• Portable instrumentation
• Precision reference for 5 V systems
• ADC and DAC reference
• Solar-powered applications
• Loop-current powered instruments

Procurement Notes

Verify the specific suffix GRU indicates the TSSOP package variant when ordering. Confirm RoHS compliance status as indicated by the Z suffix in related part numbers. Ensure the reel quantity matches project requirements. Check for any obsolescence notices or lifecycle changes directly from Analog Devices documentation before finalizing procurement plans.

Selection Notes

Select this component for applications requiring a 5 V reference with minimal power consumption. The XFET technology offers superior noise performance compared to traditional bandgap references at similar current levels. Consider the 8-lead TSSOP package for space-constrained designs. Verify that the input voltage remains within the specified 6.0 V to 15 V range for optimal regulation.

Part Context

This device belongs to the ADR29x series of precision voltage references manufactured by Analog Devices. It is pin-compatible with legacy REF02 and REF19x devices, facilitating direct upgrades in existing designs. The series includes variants with different output voltages and accuracy grades to suit various system requirements.

Replacement Considerations

Pin-compatible replacements include REF02 and REF19x series devices. Direct substitutes within the same family are ADR291 (2.5 V) and ADR292 (4.096 V). Verify electrical specifications such as noise and temperature coefficient match application needs when selecting alternatives.
