ADR03BKSZ-REEL7

Overview

The ADR03BKSZ-REEL7 is a precision series voltage reference manufactured by Analog Devices Inc., housed in an SC-70-5 surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.1% and a temperature coefficient of 3 ppm/°C. The device operates within an input voltage range of 4.5 V to 36 V and supports a maximum shunt current of 10 mA. It functions at supply currents of 1 mA across a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Delivers high-precision voltage regulation with low temperature drift characteristics suitable for sensitive analog circuits.
• Features an ultracompact five-lead SC-70 surface-mount package designed for space-constrained applications.
• Provides stable performance without requiring external capacitors, simplifying circuit design.

Applications

• Precision data acquisition systems
• High-resolution digital-to-analog converters
• Portable instrumentation

Procurement Notes

Verify the specific suffix REEL7 confirms tape-and-reel packaging when sourcing. Confirm the SC-70-5 footprint matches your PCB layout requirements. Ensure the 2.5 V output aligns with system voltage needs. Check RoHS compliance status for regulatory adherence. Validate availability through authorized distributors as stock levels vary.

Selection Notes

Select this component for applications demanding tight initial accuracy and low thermal drift in minimal board space. Compare against larger packages if higher output current or different voltage options are required. Consider the 10 mA load capability against downstream circuit demands. Evaluate the 3 ppm/°C stability against environmental temperature variations.

Part Context

This part belongs to the ADR03 family of precision bandgap references from Analog Devices. It shares pin compatibility with industry-standard REF03 devices while offering improved performance metrics. The family includes variants with different output voltages and package types to suit diverse design constraints.

Replacement Considerations

The ADR03BRZ serves as a pin-compatible alternative in an 8-SOIC package. Verify that the larger footprint accommodates your design if switching packages. Both parts share similar electrical specifications but differ in physical dimensions and mounting style.
