ADR292ERZ-REEL

Overview

The ADR292ERZ-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 ±0.07% and a maximum temperature coefficient of 8 ppm/°C. The device operates within a supply range of 4.4 V to 15 V and draws a maximum quiescent current of 15 μA. It features a low noise output of 12 μV p-p (0.1 Hz to 10 Hz) and supports a high output current of 5 mA. The component is housed in an 8-lead SOIC package and functions reliably across an extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Utilizes XFET architecture for significantly lower voltage noise compared to traditional band gap references.
• Offers very low thermal hysteresis and ultralinear temperature drift characteristics.
• Provides high output current capability of up to 5 mA while maintaining micropower consumption.
• Features pin compatibility with REF02 and REF19x series devices.

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 ordering suffix REEL against the manufacturer's documentation to confirm tape and reel packaging specifications. Ensure the E grade electrical parameters match the design requirements for initial accuracy and temperature coefficient. Confirm the 8-lead SOIC package dimensions align with the target PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a stable 4.096 V reference is required for battery-powered or portable equipment due to its low quiescent current. The XFET technology makes it suitable for applications demanding low noise performance without the complexity of higher power solutions. Consider the 8-lead SOIC package for standard surface mount assembly processes.

Part Context

This part belongs to the ADR291/ADR292 family of precision voltage references designed by Analog Devices. The ADR292 variant specifically targets applications requiring a 4.096 V output, distinguishing it from the 2.5 V ADR291 model. Both models share the same core XFET technology and package options, offering designers flexibility in system voltage planning.

Replacement Considerations

The datasheet indicates pin compatibility with REF02 and REF19x series devices. Designers should verify that the replacement part meets the specific electrical requirements for noise, accuracy, and operating voltage range before substitution.
