ADR01BRZ-REEL7

Overview

The ADR01BRZ-REEL7 is a precision series voltage reference IC manufactured by Analog Devices Inc. It provides a fixed output voltage of 10 V with an initial accuracy tolerance of ±0.05%. The device operates within an input voltage range of 12 V to 36 V and supports a maximum load current of 10 mA. Key performance specifications include a temperature coefficient of 3 ppm/°C and low noise characteristics, specifically 20 µVp-p in the 0.1 Hz to 10 Hz frequency band. It functions reliably across an extended operating temperature range from -40°C to +125°C. The unit consumes a supply current of 1 mA and is housed in an 8-SOIC surface-mount package.

Feature Summary

• Delivers high-precision 10 V reference output with tight ±0.05% initial accuracy
• Features ultra-low drift characteristics defined by a 3 ppm/°C temperature coefficient
• Provides stable operation over a wide industrial temperature range up to 125°C
• Integrates low-noise performance suitable for sensitive analog signal chains

Applications

• Unipolar, Precision DC Digital-to-Analog Conversion using AD5426/32/43 8-Bit to 12-Bit DACs
• Unipolar, Precision DC Digital-to-Analog Conversion using AD5450/1/2/3 8-14-Bit DACs
• Precision, Bipolar Configuration for AD5547/AD5557 DACs
• Precision, Bipolar Configuration for AD5450/1/2/3 8-14bit Multiplying DACs

Procurement Notes

Verify the specific suffix REEL7 indicates tape and reel packaging when sourcing components. Confirm that the 8-SOIC package dimensions match the target PCB footprint requirements. Ensure the 10 V output specification aligns with the system's reference voltage needs. Check for RoHS3 compliance status if environmental regulations apply to the manufacturing process. Validate the 12 V to 36 V input voltage range against the available power supply rails.

Selection Notes

Select this component when a fixed 10 V reference with high accuracy is required. The ±0.05% tolerance makes it suitable for applications demanding strict precision. Consider the 1 mA supply current for power-sensitive designs. The 8-SOIC package offers a balance between pin count and board space. Evaluate the 3 ppm/°C drift against thermal variations in the operational environment.

Part Context

This part belongs to the ADR01 series of precision bandgap voltage references from Analog Devices. The series includes variants with different output voltages and accuracies, such as the ADR01ARZ and ADR01AUJZ. The ADR01BRZ-REEL7 specifically denotes the 10 V output version with ±0.05% accuracy in an SOIC-8 package. It is designed for high-performance data acquisition systems requiring stable DC references.

Replacement Considerations

ADR01ARZ-REEL7: Offers 10 V output but with ±0.1% accuracy. ADR01AUJZ-REEL7: Provides 10 V output in a TSOT-23-5 package with ±0.1% accuracy.
