ADR01ARZ-REEL7

Overview

The ADR01ARZ-REEL7 is a precision series voltage reference integrated circuit manufactured by Analog Devices Inc. It provides a fixed output voltage of 10 V with an initial accuracy of 0.1%. The device operates within a supply voltage range of 12 V to 36 V and draws a typical quiescent current of 1 mA. It features a temperature coefficient of 3 PPM/°C and supports a maximum shunt current of 10 mA. The component is housed in an 8-SOIC surface-mount package and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Delivers high-precision 10 V reference output with 0.1% initial accuracy
• Maintains stable performance over wide input voltage variations up to 36 V
• Ensures long-term thermal stability with low temperature coefficient

Applications

• High-resolution analog-to-digital converter (ADC) reference sources
• Precision digital-to-analog converter (DAC) excitation circuits
• Calibration equipment requiring stable DC voltage standards

Procurement Notes

Verify the specific suffix REEL7 confirms tape-and-reel packaging compatibility with automated assembly lines. Confirm that the 8-SOIC footprint matches the target PCB design constraints. Ensure the 10 V output aligns with system requirements, as this variant is not adjustable. Check for RoHS compliance status if environmental regulations apply to the final product deployment.

Selection Notes

Select this component when a fixed 10 V precision reference is required in space-constrained designs utilizing SOIC-8 packages. It is suitable for applications demanding low drift over temperature without the need for external trimming. Consider the 1 mA quiescent current for power budget calculations in battery-operated or low-power systems where higher efficiency references might be preferred.

Part Context

This part belongs to the ADR01 family of ultracompact precision voltage references from Analog Devices. The family includes variants with different accuracies and packages, such as the ADR01BRZ for tighter tolerance or the ADR01AUJZ for TSOT-23-5 form factors. All share similar core technologies but differ in initial accuracy and physical dimensions to suit various board layout needs.

Replacement Considerations

Direct substitutes include other ADR01 series parts like ADR01ARZ for tube packaging or ADR01BRZ for improved accuracy. Cross-family replacements require verifying pinout compatibility and output voltage matching.
