ADR292FR-REEL7

Overview

The ADR292FR-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 ±0.10% and a maximum temperature coefficient of 15 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 low noise performance of 12 μV p-p (0.1 Hz to 10 Hz).

Feature Summary

• Utilizes XFET architecture for ultralow thermal hysteresis and excellent long-term stability.
• Delivers high output current up to 5 mA while maintaining micropower consumption.
• Offers low noise performance suitable for sensitive analog signal processing applications.

Applications

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

Procurement Notes

Verify that the ordering suffix REEL7 corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the specific electrical grade F specifications match the design requirements for initial accuracy and temperature drift before finalizing procurement orders.

Selection Notes

Select this component when a stable 4.096 V reference is needed with moderate precision and low power consumption. Ensure the input supply voltage remains above 4.4 V to maintain regulation. Consider the 8-lead SOIC package constraints regarding thermal dissipation if operating at elevated ambient temperatures or near maximum load currents.

Part Context

This part belongs to the ADR291/ADR292 family of precision voltage references manufactured by Analog Devices. The ADR292 variant specifically targets applications requiring a 4.096 V output, whereas the ADR291 provides 2.5 V. Both share identical pinouts and physical dimensions, facilitating direct pin-compatible replacements for legacy REF02/REF19x designs.

Replacement Considerations

The datasheet indicates pin compatibility with REF02 and REF19x series devices. Designers replacing these legacy components should verify that the lower dropout voltage and different noise characteristics of the XFET technology are acceptable for the existing circuit topology.
