ADR03AR-REEL7

Overview

The ADR03AR-REEL7 is a precision series voltage reference manufactured by Analog Devices Inc., featuring a fixed output of 2.5 V. It utilizes a bandgap architecture with an initial accuracy of 0.2% and a temperature coefficient of 3 PPM/°C. The device operates within a supply voltage range of 4.5 V to 36 V, drawing a typical quiescent current of 1 mA. It supports a maximum load current of 10 mA and functions reliably across an extended industrial temperature range from -40°C to +125°C. The component is housed in an 8-pin SOIC package.

Feature Summary

• Provides stable 2.5 V reference output with high initial accuracy
• Low temperature drift ensures consistent performance over wide thermal ranges
• Operates efficiently with low power consumption suitable for battery applications

Applications

• Precision analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage sources
• High-resolution instrumentation systems
• Medical equipment requiring stable bias voltages

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required packaging and tolerance grades. Confirm availability status through authorized distributors as supply conditions may vary. Ensure proper handling procedures are followed during storage and installation to maintain component integrity.

Selection Notes

Select this component when a fixed 2.5 V reference with moderate precision is required. Consider the 3 PPM/°C temperature coefficient for environments with significant thermal fluctuations. Evaluate the 1 mA quiescent current against system power budgets. Verify that the SOIC-8 package fits the design constraints.
