ADR01AUJZ-REEL7

Overview

The ADR01AUJZ-REEL7 is a precision series voltage reference manufactured by Analog Devices Inc., housed in a TSOT-23-5 surface-mount package. It provides a fixed output voltage of 10V with an initial accuracy tolerance of ±0.1%. The device operates within an input voltage range of 12V to 36V and draws a supply current of 1mA. Key performance specifications include a temperature coefficient of 25ppm/°C and low-frequency noise of 20µVp-p from 0.1Hz to 10Hz. It supports a maximum output current of 10mA and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Delivers high-precision 10V reference output with ±0.1% initial accuracy for critical measurement applications.
• Features ultracompact TSOT-23-5 packaging suitable for space-constrained printed circuit board designs.
• Provides robust thermal stability with a temperature coefficient of 25ppm/°C over the industrial operating range.

Applications

• Precision analog-to-digital converter (ADC) reference sources
• High-resolution digital-to-analog converter (DAC) excitation
• Medical instrumentation signal conditioning circuits

Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when sourcing components. Confirm that the AUJZ designation corresponds to the TSOT-23-5 package variant required for your layout. Ensure compatibility with the 12V to 36V input voltage range during system design validation. Check for RoHS compliance status as indicated in official documentation before final procurement approval.

Selection Notes

Select this component when a stable 10V reference is required in a minimal footprint form factor. The ±0.1% accuracy suits applications demanding tight tolerance without requiring laser trimming. Consider the 1mA supply current for battery-operated systems where power efficiency is secondary to precision. Evaluate the 25ppm/°C drift against environmental temperature variations in the target deployment scenario.

Part Context

This part belongs to the ADR01 family of precision voltage references, which includes variants with different accuracies and packages. The AUJZ suffix specifically denotes the TSOT-23-5 thin small-outline transistor package. The REEL7 suffix identifies the bulk reel packaging format used for automated assembly processes in manufacturing environments.

Replacement Considerations

The ADR01BRZ-REEL7 offers similar 10V output but utilizes an 8-SOIC package with higher ±0.05% accuracy. Verify pinout compatibility and physical dimensions if substituting into existing PCB footprints designed for the TSOT-23-5 form factor.
