Overview
The REF43GS-REEL7 is a low power precision voltage reference providing a stable 2.5 V output independent of supply voltage, load conditions, or ambient temperature variations. It features an initial accuracy of 0.10% and a temperature coefficient of 25 ppm/°C. The device operates within a supply voltage range of 4.5 V to 40 V and draws a maximum supply current of 450 µA. It supports a maximum output current of 20 mA and functions reliably across an extended industrial temperature range from -40°C to +85°C.
Feature Summary
- Zener-zap trimming ensures tight output tolerances and low thermal drift for both output voltage and temperature coefficient.
- Unique curvature correction circuit reduces the thermal curvature characteristic of many previous bandgap references.
Applications
- Reference level for 8-bit data acquisition systems
- Reference level for 10-bit data acquisition systems
- Reference level for 12-bit data acquisition systems
Procurement Notes
Verify the specific suffix against official documentation to confirm package type and reel quantity. Confirm RoHS compliance status as indicated by the 'Z' designation if applicable. Check manufacturer availability and lifecycle status prior to procurement planning.
Selection Notes
Select this component when a stable 2.5 V reference with low power consumption is required for precision measurement applications. Ensure the operating environment falls within the specified -40°C to +85°C temperature range and that the supply voltage remains between 4.5 V and 40 V.
Part Context
This part belongs to the REF43 series of low power precision voltage references manufactured by Analog Devices Inc. The series includes various package options such as hermetic DIP, plastic DIP, and SOIC. The REF43GS-REEL7 specifically denotes the 8-pin SOIC package variant supplied in a reel format.
Replacement Considerations
Direct replacements include other variants within the REF43 family such as REF43FZ, REF43GZ, REF43GP, REF43GS, REF43GSZ, and REF43NBC, depending on required accuracy, package type, and initial temperature coefficient specifications.
FAQ
How does the REF43 achieve low thermal drift?
Tight output tolerances and low thermal drift are assured by zener-zap trimming of both the output voltage and its temperature coefficient.
What is the purpose of the curvature correction circuit?
The unique curvature correction circuit reduces the thermal curvature which is characteristic of many previous bandgap references.
