ADR01ARZ

Overview

The ADR01ARZ is a precision series voltage reference IC manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It provides a fixed output voltage of 10 V with an initial accuracy tolerance of ±0.1%. The device operates within an extended temperature range from -40°C to +125°C and features a low temperature coefficient of 3 ppm/°C. It draws a supply current of 1 mA and supports a maximum input voltage of 36 V, with a maximum shunt current capability of 10 mA.

Feature Summary

• Delivers high-precision 10 V reference output with tight initial accuracy tolerance.
• Utilizes series bandgap architecture for stable performance across wide temperature ranges.
• Offers low temperature coefficient characteristics for minimal drift over thermal variations.

Applications

• High-resolution data acquisition systems requiring stable reference sources
• Precision analog-to-digital converter (ADC) excitation circuits
• Calibration equipment needing accurate voltage standards

Procurement Notes

Verify the specific suffix 'ARZ' to confirm the SOIC-8 package and lead-free RoHS compliance status. Confirm availability as distribution channels may list limited stock or restricted supply conditions. Ensure the operating environment stays within the specified -40°C to +125°C range to maintain the stated 3 ppm/°C temperature coefficient performance.

Selection Notes

Select this component when a fixed 10 V output is required with ±0.1% initial accuracy. It is suitable for designs needing low power consumption at 1 mA supply current. Consider the 8-SOIC package for surface-mount assembly constraints. Verify that the 36 V maximum input voltage rating accommodates the system's supply rails.

Part Context

This part belongs to the ADR01 series of precision voltage references from Analog Devices. It is designed for applications demanding high stability and low noise. The series includes variants with different output voltages and packages, but the ADR01ARZ specifically targets the 10 V output requirement in a standard SOIC footprint.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family if package changes are acceptable. Verify that any substitute maintains the 10 V output and similar accuracy specifications.
