ADR292GRUZ-REEL7

Overview

The ADR292GRUZ-REEL7 is a low noise, micropower precision voltage reference utilizing XFET architecture. It provides a fixed output of 4.096 V with an initial accuracy of ±0.15% and a maximum temperature coefficient of 25 ppm/°C. The device operates within a supply range of 4.4 V to 15 V and draws a maximum quiescent current of 18 μA across the extended industrial temperature range of −40°C to +125°C. It features a high output current capability of 5 mA and exhibits low noise performance of 12 μV p-p from 0.1 Hz to 10 Hz.

Feature Summary

• Utilizes XFET architecture for ultralow thermal hysteresis and excellent long-term stability.
• Provides high output current capability of 5 mA suitable for driving various loads.
• Operates with minimal supply current, making it ideal for battery-powered applications.

Applications

• Portable instrumentation
• Precision reference for 3 V and 5 V systems
• Analog-to-digital and digital-to-analog converter reference
• Solar-powered applications

Procurement Notes

Verify the specific electrical grade (G) corresponding to the ±0.15% accuracy and 25 ppm/°C temperature coefficient when sourcing. Confirm that the 8-lead TSSOP package matches the PCB footprint requirements. Ensure the input supply voltage remains above the minimum operating threshold of 4.4 V to maintain regulation. Check datasheet specifications for thermal management if operating near maximum junction temperatures.

Selection Notes

Select this component when a stable 4.096 V reference is required with low power consumption. The G-grade offers a balance of accuracy and cost for general precision applications. Consider the 8-lead TSSOP package for space-constrained designs. Verify compatibility with system supply voltages, as the minimum operating voltage is higher than the ADR291 series.

Part Context

This part belongs to the ADR291/ADR292 family of precision voltage references. While the ADR291 provides a 2.5 V output, the ADR292 variant delivers 4.096 V. Both share the same XFET technology and pinout configurations, allowing for design flexibility. The GRUZ suffix indicates the G-grade electrical specification and the 8-lead TSSOP package type.

Replacement Considerations

Pin-compatible alternatives include other members of the ADR29x family such as the ADR291GRZ for 2.5 V applications or the REF19x series, though electrical characteristics like noise and current may differ. Verify that any substitute meets the specific 4.096 V output requirement and package dimensions.
