ADR293GRUZ

Overview

The ADR293GRUZ is a low noise, micropower precision voltage reference providing a fixed 5.0 V output in an 8-lead TSSOP package. It operates from a 6.0 V to 15 V supply with a maximum quiescent current of 15 μA. The device delivers up to 5 mA load current and features a typical noise of 15 μV p-p (0.1 Hz to 10 Hz). Electrical grades offer initial accuracy ranging from ±0.06% to ±0.20% and temperature coefficients between 8 ppm/°C and 25 ppm/°C. It functions within an extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Utilizes XFET architecture for low noise and ultralinear temperature drift
• Provides high output current capability of 5 mA
• Features very low thermal hysteresis and excellent long-term stability
• Pin-compatible with REF02 and REF19x series devices

Applications

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

Procurement Notes

Verify the specific electrical grade suffix (E, F, or G) required for your application's accuracy and temperature coefficient needs. Confirm that the 8-lead TSSOP package option matches your PCB footprint requirements. Ensure the ordering quantity aligns with reel specifications if purchasing bulk quantities. Check RoHS compliance status as indicated by the Z suffix.

Selection Notes

Select this component when a stable 5 V reference is needed with minimal power consumption. The XFET technology offers superior noise performance compared to traditional bandgap references at similar currents. Consider the available accuracy grades to balance cost against precision requirements. Verify that the input voltage remains within the specified 6.0 V to 15 V range for optimal regulation.

Part Context

The ADR293GRUZ belongs to the ADR29x family of precision voltage references manufactured by Analog Devices. This series includes variants with different output voltages such as 2.5 V and 4.096 V. The GRUZ designation specifically indicates the 8-lead TSSOP package with RoHS compliance. These devices are designed for applications requiring high stability and low power consumption.

Replacement Considerations

The datasheet notes pin compatibility with REF02 and REF19x series devices. When substituting, verify that the replacement part meets the specific accuracy and temperature coefficient requirements of the original design. Ensure the new component supports the same 5 V output and 5 mA load current capabilities.
