Overview
The REF03GSZ is a precision voltage reference integrated circuit manufactured by Analog Devices Inc. It provides a fixed output voltage of 2.5V with an initial accuracy of 0.1%. The device operates within a supply voltage range of 4.5V to 40V and draws a maximum quiescent current of 450µA. It features a temperature coefficient of 25ppm/°C and delivers an output current capability of 20mA. The component is housed in an 8-SOIC package and is rated for operation between -40°C and +85°C.
Feature Summary
- Provides a stable 2.5V reference output with high initial accuracy
- Operates over a wide input voltage range up to 40V
- Designed for low power consumption applications
Applications
- Precision analog-to-digital converter (ADC) references
- Digital-to-analog converter (DAC) voltage sources
- High-accuracy measurement instrumentation systems
Procurement Notes
Verify the specific suffix and packaging configuration against official manufacturer documentation before procurement, as availability may vary. Confirm that the 8-SOIC package dimensions match your PCB layout requirements. Ensure the operating temperature range meets your system specifications. Check for any recent product change notices regarding manufacturing sites or materials.
Selection Notes
Select this component when a fixed 2.5V reference with 0.1% initial accuracy is required. Consider the 450µA quiescent current draw for power budget calculations. Verify that the 20mA output current capability satisfies the load requirements of the connected circuitry. Ensure the 8-SOIC package fits the available board space.
Part Context
This part belongs to the REF43 series of precision voltage references from Analog Devices. The series is characterized by its ability to provide accurate reference voltages in a compact surface-mount package. The GSZ suffix typically indicates a lead-free RoHS-compliant version in an SOIC package.
Replacement Considerations
Consult official Analog Devices documentation for verified cross-reference part numbers. Do not assume functional compatibility with other manufacturers' devices without verifying electrical parameters and pin configurations.
