ADR03AKSZ-REEL7

Overview

The ADR03AKSZ-REEL7 is a precision series voltage reference from Analog Devices, delivering a fixed output of 2.5 V with an initial accuracy of ±0.2%. It operates within a supply voltage range of 4.5 V to 36 V and draws a typical quiescent current of 1 mA. The device features a low temperature coefficient of 3 ppm/°C and supports a maximum load current of 10 mA. Designed for surface-mount applications, it is housed in a compact SC-70-5 package and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides stable 2.5 V reference output with high initial accuracy
• Maintains performance over wide input voltage and temperature ranges
• Optimized for low power consumption in portable designs

Applications

• Precision data acquisition systems
• Portable instrumentation
• Battery-powered measurement devices

Procurement Notes

Verify the specific suffix 'REEL7' against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with SC-70-5 footprint requirements during PCB layout. Confirm that the 2.5 V output aligns with system reference needs. Validate thermal management strategies for operation up to +125°C. Cross-check RoHS compliance status with current regulatory standards before integration.

Selection Notes

Select this component when a compact, low-power voltage reference is required for space-constrained designs. The SC-70-5 package offers significant size reduction compared to traditional SOIC options. The 3 ppm/°C temperature coefficient ensures stability in varying environmental conditions. Consider the 10 mA load capability for driving downstream ADCs or DACs without external buffering in most standard applications.

Part Context

This part belongs to the ADR03 series of precision bandgap voltage references manufactured by Analog Devices. The series includes variants with different output voltages and packages. The ADR03AKSZ-REEL7 specifically denotes the 2.5 V version in a SC-70-5 reel configuration. It shares core architectural similarities with other members like the ADR03BRZ but differs in packaging and initial accuracy specifications.

Replacement Considerations

Direct substitutes include ADR03BRZ for SOIC-8 packaging or ADR03WARZ-RL for alternative reel configurations. Verify pinout compatibility and thermal characteristics when transitioning between package types. Ensure that the ±0.2% accuracy meets design tolerances if replacing higher-precision variants.
