Overview
The ADR293GRZ-REEL7 is a low noise, micropower precision voltage reference providing a stable 5.0 V output from a 6.0 V to 15 V supply range. It utilizes XFET architecture for improved performance over traditional band gap references. The device offers an initial accuracy of ±0.20% and a maximum temperature coefficient of 25 ppm/°C. Quiescent current is limited to 15 μA maximum, supporting battery-powered applications. It delivers up to 5 mA of load current with low thermal hysteresis and excellent long-term stability.
Feature Summary
- Utilizes XFET architecture for significantly lower voltage noise and ultralinear temperature drift compared to band gap references.
- Provides high output current capability of 5 mA while maintaining extremely low quiescent supply current.
- Features very low thermal hysteresis and excellent long-term stability for reliable precision operation.
Applications
- Portable instrumentation
- Precision reference for 5 V systems
- ADC and DAC reference
- Solar-powered applications
Procurement Notes
Verify the specific suffix REEL7 indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as indicated by the Z suffix in the part number. Ensure the ordering quantity matches the manufacturer's standard reel size requirements for this specific package variant.
Selection Notes
Select this component for designs requiring a fixed 5.0 V reference with minimal power consumption. Consider the 8-lead SOIC package for surface mount assembly. Evaluate the 25 ppm/°C temperature coefficient against system accuracy requirements across the full industrial temperature range.
Part Context

FAQ
What is the typical voltage noise performance of the ADR293?
The typical voltage noise is 15 μV p-p measured over the 0.1 Hz to 10 Hz frequency band.
How does the XFET architecture benefit the ADR293?
The XFET architecture provides one-quarter the voltage noise of band gap references at the same current, along with very low thermal hysteresis and excellent long-term stability.
