Overview
The ADR03AUJ-R2 is a precision series voltage reference from Analog Devices, delivering a fixed 2.5 V output in an ultracompact TSOT-23-5 package. It features high initial accuracy of 0.2% and a low temperature coefficient of 3 ppm/°C. The device operates with a maximum input voltage of 36 V and supports a maximum shunt current of 10 mA. It functions reliably across an extended industrial temperature range from -40°C to +125°C while consuming only 1 mA of supply current.
Feature Summary
- Ultracompact TSOT-23-5 packaging for space-constrained designs
- High precision with 0.2% initial accuracy and 3 ppm/°C temperature stability
- Wide operating input voltage range up to 36 V
- Extended industrial temperature operation from -40°C to +125°C
Applications
- Precision data acquisition systems
- Portable instrumentation
- Battery-powered measurement devices
- Industrial process control loops
Procurement Notes
Verify the specific suffix against official documentation to confirm pinout and electrical characteristics match your design requirements. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the component meets RoHS compliance standards required for your target market. Cross-reference the datasheet revision date to ensure access to the latest technical specifications and application notes.
Selection Notes
Select this component when a stable 2.5 V reference is required in a minimal footprint. The 3 ppm/°C drift ensures long-term stability without external trimming. The wide input voltage capability allows flexibility in power supply design. Consider the 1 mA quiescent current for battery life calculations in portable applications requiring precise analog front-end referencing.
Part Context
The ADR03AUJ-R2 belongs to the ADR03 family of precision bandgap references. This series is designed for applications demanding high accuracy and stability in small form factors. The AUJZ/R2 designation indicates the specific voltage, package type, and reel packaging configuration used by Analog Devices for distribution.
Replacement Considerations
Check for ADR03AUJZ-REEL7 as a potential alternative within the same product line. Verify that substitute components maintain identical pinouts and electrical parameters such as temperature coefficient and initial accuracy before integration.
