ADR292FRZ-REEL7

Overview

The ADR292FRZ-REEL7 is a low noise, micropower precision voltage reference from the Analog Devices ADR292 series. It utilizes XFET architecture to deliver a fixed output voltage 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 typical quiescent current of 12 μA. It features a low noise profile of 12 μV p-p (0.1 Hz to 10 Hz) and supports a maximum load current of 5 mA. Packaged in an 8-lead SOIC, it 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.
• Provides high output current capability up to 5 mA while maintaining low quiescent power consumption.
• Offers excellent long-term stability and very low thermal hysteresis characteristics.

Applications

• Precision reference for analog-to-digital and digital-to-analog converters
• Portable instrumentation powered by batteries
• Solar-powered applications requiring stable voltage regulation

Procurement Notes

Verify that the specific ordering suffix matches the required package type and reel quantity. Confirm the electrical grade aligns with the necessary accuracy and temperature coefficient specifications for the target application. Ensure compatibility with the system's input voltage range and load requirements before finalizing procurement.

Selection Notes

Select this component when a stable 4.096 V reference is needed with low power consumption. Consider the XFET technology benefits regarding noise and drift if higher precision than standard band gap references is required. Evaluate the 8-lead SOIC package suitability for the available board space and thermal management constraints.

Part Context

This part belongs to the ADR291/ADR292 family of precision voltage references designed for battery-operated systems. The ADR292 variant specifically provides a 4.096 V output, making it suitable for driving ADCs and DACs that require standard reference voltages. The FRZ designation indicates the F-grade accuracy level packaged in an 8-lead SOIC.

Replacement Considerations

The datasheet notes pin-compatibility with REF02 and REF19x series devices. Verify that substitute components meet the specific 4.096 V output requirement and match the 15 ppm/°C temperature coefficient limit.
