ADR292FRZ-REEL

Overview

The ADR292FRZ-REEL is a low noise, micropower precision voltage reference from Analog Devices 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 on a supply range of 4.4 V to 15 V with a maximum supply current of 15 μA. It delivers up to 5 mA of load current and features low noise performance of 12 μV p-p (0.1 Hz to 10 Hz). Packaged in an 8-lead SOIC, it functions within an extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Utilizes XFET architecture for low noise and ultralow thermal drift
• Provides high output current capability of 5 mA
• Pin-compatible with REF02 and REF19x series devices

Applications

• Portable instrumentation

• Analog-to-digital and digital-to-analog converter reference
• Solar-powered applications
• Loop-current-powered instruments

Procurement Notes

Verify the specific suffix REEL against the manufacturer's ordering guide to confirm tape and reel packaging specifications. Ensure the F grade designation matches the required initial accuracy and temperature coefficient parameters for your design. Cross-reference the package type to confirm compatibility with your PCB footprint and assembly process.

Selection Notes

Select this component when a stable 4.096 V reference is needed with low power consumption. The XFET technology offers superior noise performance compared to traditional bandgap references at similar currents. Consider the minimum input-output voltage differential requirements under varying load conditions to ensure proper regulation across the specified temperature range.

Part Context

This part belongs to the ADR291/ADR292 family of precision voltage references. The ADR292 variant specifically provides a 4.096 V output, whereas the ADR291 provides 2.5 V. Both share the same pinout and core XFET technology, allowing for flexible system design where different reference voltages are required within the same product line.

Replacement Considerations

The datasheet indicates pin-compatibility with REF02 and REF19x series devices. Verify electrical specifications such as noise, accuracy, and operating voltage ranges before substituting these legacy parts to ensure performance requirements are met.
