REF03GSZ-REEL

Overview

The REF03GSZ-REEL is a precision series voltage reference IC manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy tolerance of ±0.1%. The device operates within a supply voltage range of 4.5 V to 40 V and draws a typical supply current of 450 µA. It features a temperature coefficient of 25 ppm/°C and exhibits low noise characteristics, specified at 10 µVrms over the 0.1 Hz to 10 Hz frequency band. The component supports a maximum output current of 20 mA and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Delivers a stable 2.5 V reference output with high initial accuracy of ±0.1%.
• Operates efficiently with low power consumption of 450 µA supply current.
• Provides robust performance with a wide input voltage range up to 40 V.
• Ensures signal integrity through low noise specifications suitable for precision applications.

Applications

• High-resolution analog-to-digital converter (ADC) reference sources
• Precision data acquisition systems requiring stable voltage baselines
• Calibration equipment needing accurate reference potentials
• Instrumentation amplifiers utilizing precise voltage references

Procurement Notes

Verify the specific suffix 'GSZ' confirms the tape and reel packaging format required for automated assembly processes. Confirm that the 8-SOIC footprint matches the target PCB design constraints. Ensure the operating environment remains within the specified -40°C to +85°C temperature range to maintain the stated accuracy and stability parameters during deployment.

Selection Notes

Select this component when a fixed 2.5 V output is required with tight tolerance specifications. The low noise profile makes it suitable for sensitive measurement circuits. Consider the 450 µA quiescent current for power-constrained designs. The wide input voltage capability allows flexibility in system power architecture without compromising reference stability under varying load conditions.

Part Context

This part belongs to the REF03 series of precision voltage references from Analog Devices. It shares functional similarities with other members like the REF02CSZ but offers a different fixed output voltage. The GSZ suffix indicates a lead-free, RoHS-compliant variant packaged in tape and reel for efficient surface-mount technology integration into electronic assemblies.

Replacement Considerations

Direct substitutes include other Analog Devices precision references such as the ADR03 series or REF43 series, provided they match the 2.5 V output, SOIC-8 package, and electrical performance requirements. Verify pin compatibility and thermal characteristics before substitution.
