ADR293GRUZ-REEL

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 from a 6.0 V to 15 V supply with a maximum quiescent current of 15 μA. It offers high output current capability up to 5 mA and features low noise of 15 μV p-p (0.1 Hz to 10 Hz). The component is available in an 8-lead TSSOP package and supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Utilizes XFET architecture for low noise and ultralinear temperature drift
• Provides stable 5.0 V output with high accuracy grades
• Micropower consumption suitable for battery-powered instrumentation
• 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 electrical grade (E, F, or G) required for your application, as initial accuracy and temperature coefficient vary by grade. Confirm the package type matches your PCB footprint, specifically the 8-lead TSSOP option indicated by the GRUZ suffix. Ensure the reel quantity aligns with production needs. Cross-reference the datasheet revision to confirm specifications have not changed since manufacturing.

Selection Notes

Select this component when a stable 5 V reference is needed with minimal power consumption. Consider the XFET technology benefits regarding thermal hysteresis and long-term stability compared to band gap alternatives. Evaluate the required accuracy grade against cost constraints. Ensure the input voltage remains within the 6.0 V to 15 V operating range for optimal regulation.

Part Context

The ADR293 belongs to the ADR29x series of precision voltage references manufactured by Analog Devices. This family includes variants with different output voltages such as 2.5 V and 4.096 V. The GRUZ suffix denotes the 8-lead TSSOP package variant, while REEL7 indicates tape and reel packaging. These devices are designed to replace older three-terminal references like the REF02.

Replacement Considerations

Pin-compatible with REF02/REF19x series devices.
