Overview
The ADR03BUJ-R2 is a precision series voltage reference integrated circuit manufactured by Analog Devices Inc. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.2%. The device features a low temperature coefficient of 3 PPM/°C and operates within a supply voltage range up to 36 V. It draws a typical quiescent current of 1 mA and supports a maximum shunt current of 10 mA. The component is housed in a TSOT-23-5 surface-mount package and is rated for operation from -40°C to +125°C.
Feature Summary
- Delivers high-precision voltage regulation with tight initial accuracy specifications
- Maintains stable performance across wide industrial temperature ranges
- Utilizes ultracompact surface-mount packaging for space-constrained designs
Applications
- Precision analog-to-digital converter (ADC) reference sources
- Data acquisition systems requiring stable voltage baselines
- Instrumentation amplifier biasing circuits
Procurement Notes
Verify the specific suffix configuration against official Analog Devices documentation to ensure compatibility with required tolerance and thermal specifications. Confirm RoHS compliance status as manufacturing updates may affect regulatory markings. Cross-reference the complete part number with authorized distributors to validate availability and authenticity before procurement.
Selection Notes
Select this component when a compact, high-accuracy reference is needed for low-power applications. Ensure the input voltage does not exceed the maximum rating of 36 V. Consider the thermal management requirements given the operating temperature range. Verify that the 1 mA quiescent current aligns with system power budget constraints.
Part Context
This part belongs to the ADR03 family of precision bandgap references designed for ultracompact applications. It shares architectural similarities with other members like the ADR03AUJZ-REEL7 but differs in specific ordering suffixes that denote package variations or reel configurations. The family targets high-performance signal conditioning tasks.
Replacement Considerations
Direct substitutes include other ADR03 variants such as ADR03AUJZ-REEL7, provided the pinout and electrical characteristics match the design requirements. Verify that alternative packages maintain the same thermal and mechanical constraints.
