ADR293GRUZ-REEL7

Overview

The ADR293GRUZ-REEL7 is a low noise, micropower precision voltage reference providing a fixed 5.0 V output. It utilizes XFET architecture for superior performance over traditional band gap references. The device operates within a supply range of 6.0 V to 15 V with a maximum quiescent current of 15 μA. It delivers up to 5 mA of load current and features a typical noise of 15 μV p-p (0.1 Hz to 10 Hz). The unit is housed in an 8-lead TSSOP package and functions across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Utilizes XFET architecture for low noise and ultralinear temperature drift
• Micropower operation with 15 μA maximum supply current
• High output current capability of 5 mA
• Pin-compatible with REF02/REF19x series

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 GRUZ indicates the 8-lead TSSOP package variant rather than the SOIC version. Confirm RoHS compliance status as indicated by the Z suffix. Ensure the REEL7 designation matches required tape and reel quantities for automated assembly processes. Cross-reference the datasheet revision D specifications against current procurement requirements.

Selection Notes

Select this component when a stable 5.0 V reference is required with minimal power consumption. The XFET technology offers lower noise compared to standard band gap references at similar currents. Consider the 5 mA output drive capability for direct loading or op-amp buffering. Verify that the input voltage remains above 6.0 V to ensure proper regulation across the full operating temperature range.

Part Context

This part belongs to the ADR29x family of precision voltage references manufactured by Analog Devices Inc. The family includes variants with different output voltages such as 2.5 V and 4.096 V. The GRUZ suffix specifically denotes the thin shrink small outline package option, distinguishing it from the standard narrow body SOIC packaging found in other model numbers within the same product line.

Replacement Considerations

The datasheet notes pin compatibility with the REF02 and REF19x series. Designers replacing legacy components should verify electrical parameter alignment, particularly regarding initial accuracy grades and temperature coefficients, before substituting these parts.
