Overview
The REF43GS is a low power precision voltage reference providing a stable 2.5 V output, suitable for 8-, 10- and 12-bit data acquisition systems. It features an initial accuracy of 0.10% and a temperature coefficient of 25ppm/°C. The device operates within a supply voltage range of 4.5V to 40V with a supply current of 450µA. Output current capability reaches 20 mA. Noise performance is specified at 10µVrms from 10Hz to 10kHz. Operating temperature range spans -40°C to +85°C.
Feature Summary
- Zener-zap trimming ensures tight output tolerances and low thermal drift.
- Unique curvature correction circuit reduces thermal curvature characteristic of 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 package suffix 'S' corresponds to the 8-Pin SOIC configuration as listed in the ordering guide. Confirm RoHS compliance status indicated by the 'Z' suffix if applicable to the exact part number variant being procured. Ensure ESD precautions are observed during handling due to sensitivity.
Selection Notes
Select this component when a fixed 2.5 V reference is required for moderate precision applications. The 25ppm/°C temperature coefficient suits general-purpose data acquisition. Consider higher accuracy models like the REF43FZ if tighter tolerance or lower drift is necessary for the design requirements.
Part Context
The REF43 series includes variants such as REF43FZ, REF43GZ, REF43GP, and REF43GS. These share the same core functionality but differ in accuracy, package type, and temperature coefficient specifications. The REF43GS specifically denotes the 0.10% accuracy version in an 8-Pin SOIC package.
Replacement Considerations
REF43FZ offers 0.06% accuracy and 10ppm/°C drift in a hermetic DIP package. REF43GZ provides 0.10% accuracy in a hermetic DIP package. REF43GP offers 0.10% accuracy in a plastic DIP package.
