Overview
The ADR293GRU 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. Utilizing XFET architecture, it achieves a maximum quiescent current of 15 μA and delivers up to 5 mA of load current. The device offers an initial accuracy of ±0.20% with a maximum temperature coefficient of 25 ppm/°C. It operates within an extended industrial temperature range of −40°C to +125°C and features low thermal hysteresis.
Feature Summary
- XFET architecture provides ultralow noise and very low thermal hysteresis compared to traditional band gap references.
- Micropower design ensures minimal energy consumption, making it suitable for battery-powered instrumentation.
- High output capability allows sourcing up to 5 mA while maintaining precise regulation.
Applications
- Portable instrumentation
- Precision reference for 5 V systems
- ADC and DAC reference
- Solar-powered applications
Procurement Notes
Verify the specific suffix 'RU' corresponds to the 8-lead TSSOP package configuration required for your layout. Confirm that the G-grade electrical specifications meet your accuracy and drift requirements. Ensure input voltage remains within the specified operational limits to maintain performance.
Selection Notes
Select this component when low noise and high precision are critical in space-constrained portable designs. The TSSOP package offers a compact footprint compared to SOIC alternatives. Consider the thermal resistance characteristics if operating near maximum junction temperatures.
Part Context
This part belongs to the ADR29x series of precision voltage references manufactured by Analog Devices. It shares architectural similarities with other members like the ADR291 and ADR292 but is specifically optimized for a 5.0 V output level. The series utilizes proprietary XFET technology for superior stability.
Replacement Considerations
Pin-compatible with REF02 and REF19x series devices. Direct substitutes include other ADR29x variants such as ADR293ERZ or ADR293GRZ depending on package preference and grade requirements.
