ADR02BR

Overview

The ADR02BR is a precision bandgap voltage reference from Analog Devices, delivering a fixed 5.0 V output. It features an initial accuracy of ±0.1% and a low temperature coefficient of 3 ppm/°C. The device operates within a wide input voltage range of 7.0 V to 36.0 V and supports a maximum shunt current of 10 mA. It functions reliably across an extended temperature range from -40°C to +125°C with a quiescent current of approximately 1 mA. This component is housed in an 8-lead SOIC package.

Feature Summary

• Provides high-precision 5.0 V reference with ±0.1% initial accuracy
• Features ultralow temperature coefficient for enhanced thermal stability
• Supports wide operating input voltage up to 36 V
• Delivers high output current capability of 10 mA

Applications

• Precision data acquisition systems
• High-resolution analog-to-digital converters
• Industrial process control instrumentation
• PCMCIA cards and space-constrained electronics

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and reel specifications. Confirm availability status as supply may be limited or subject to factory order constraints. Ensure compatibility with existing board layouts by checking pinout alignment with legacy REF02 equivalents if applicable.

Selection Notes

Select this component when high accuracy and low drift are critical for signal integrity. The 3 ppm/°C coefficient suits applications requiring minimal thermal adjustment. Verify that the 10 mA output current meets load requirements without exceeding power dissipation limits in the chosen package configuration.

Part Context

Part of the ADR0x series of ultracompact precision references. Designed as a drop-in replacement for industry-standard REF02 devices while offering improved performance metrics. Suitable for general-purpose applications where size and precision are balanced priorities.

Replacement Considerations

Directly compatible with REF02 pinouts. Check for equivalent parts in the ADR01, ADR03, or ADR06 families if different voltage outputs are required.
