ADR293GRU-REEL

Overview

The ADR293GRU-REEL 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 supply current of 15 μA. It features an initial accuracy of ±0.20% and a maximum temperature coefficient of 25 ppm/°C. The component supports a high output current of 5 mA and exhibits typical voltage noise of 15 μV p-p from 0.1 Hz to 10 Hz. It is housed in an 8-lead TSSOP package and functions across an extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Utilizes XFET architecture to achieve significantly lower voltage noise and ultralinear temperature drift compared to standard band gap references.
• Provides high output drive capability with a maximum load current of 5 mA while maintaining ultra-low quiescent supply current.
• Features very low thermal hysteresis and excellent long-term stability for reliable operation in demanding environments.

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. Confirm RoHS compliance status as indicated by the Z suffix. Ensure the reel quantity matches project requirements. Check for any obsolescence notices or lifecycle changes directly from Analog Devices documentation before finalizing procurement plans.

Selection Notes

Select this component when a stable 5 V reference is required with minimal power consumption. The XFET technology offers advantages in noise-sensitive applications. Consider the 8-lead TSSOP package for space-constrained PCB layouts. Verify that the input voltage remains within the specified 6.0 V to 15 V range for proper regulation.

Part Context

The ADR293 series includes variants with different output voltages and accuracies. The ADR291 provides 2.5 V, while the ADR292 offers 4.096 V. All share similar XFET-based performance characteristics. This specific model is part of the broader portfolio designed for portable and battery-powered equipment requiring high precision.

Replacement Considerations

The datasheet notes pin compatibility with REF02 and REF19x series devices. Designers replacing legacy references should verify pinout alignment and ensure electrical specifications meet system requirements without additional circuit modifications.
