REF43GS-REEL

Overview

The REF43GS-REEL is a low power precision voltage reference providing a stable 2.5 V output, housed in an 8-pin SOIC package with a standard reel quantity of 2,500 units. It features an initial accuracy of ±0.1% and a temperature coefficient of 25 ppm/°C across an operating temperature range of -40°C to +85°C. The device operates within an input voltage range of 4.5 V to 40 V, drawing a supply current of 450 µA while delivering up to 20 mA of output current.

Feature Summary

• Utilizes zener-zap trimming for both output voltage and temperature coefficient to ensure tight tolerances and low thermal drift.
• Incorporates a unique curvature correction circuit that reduces the thermal curvature typically found in bandgap references.
• Provides a stable 2.5 V output independent of variations in supply voltage, load conditions, or ambient temperature.

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 ordering suffix against the manufacturer's official documentation to confirm packaging details and environmental compliance status. Confirm that the component meets all required electrical specifications for the intended application before procurement. Ensure proper electrostatic discharge precautions are observed during handling due to device sensitivity.

Selection Notes

Select this component when a fixed 2.5 V reference with high precision and low power consumption is required. The ±0.1% accuracy and 25 ppm/°C drift make it suitable for applications demanding stability over varying temperatures. Consider the 8-SOIC package dimensions and the 4.5 V to 40 V input range compatibility with the system power supply.

Part Context

This part belongs to the REF43 series of low power precision voltage references manufactured by Analog Devices Inc. The series includes various packages such as DIP and SOIC, with options for hermetic and plastic constructions. The REF43GS-REEL specifically denotes the surface-mount SOIC variant supplied in a standard reel format.

Replacement Considerations

Other members of the REF43 family, such as REF43GZ or REF43GP, offer identical electrical characteristics but differ in package type (DIP) or construction material (hermetic vs. plastic). Verify pinout and physical footprint compatibility if substituting with these variants.
