REF03GSZ-REEL7

Overview

The REF03GSZ-REEL7 is a precision series voltage reference manufactured by Analog Devices Inc., housed in an SOIC-8 surface-mount package. It delivers a fixed output voltage of 2.5 V with an initial accuracy of 0.6%. The device operates within an input voltage range up to 36 V and supports a maximum shunt current of 10 mA. It functions reliably across a temperature range from -40°C to +85°C, maintaining a temperature coefficient of 50 PPM/°C.

Feature Summary

• Provides stable series reference voltage for high-precision applications
• Operates with wide input voltage capability up to 36 V
• Designed for surface-mount integration via SOIC-8 packaging

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage standards
• Calibration equipment requiring stable reference potentials

Procurement Notes

Verify component status as the manufacturer has issued discontinuation notifications indicating end-of-life status. Confirm availability through authorized distributors or surplus channels, as standard supply may be restricted. Ensure compatibility with existing designs before procurement due to potential obsolescence constraints.

Selection Notes

Select this component when a 2.5 V reference with moderate precision is required in an SOIC-8 form factor. Consider the 50 PPM/°C temperature coefficient and 0.6% initial accuracy against application requirements. Evaluate the 36 V maximum input voltage limit for power supply headroom needs.

Part Context

This part belongs to the REF03 series of precision voltage references from Analog Devices. It shares the core electrical characteristics of the REF03 family but is specifically packaged in SOIC-8 and supplied in reel format for automated assembly processes.
