Overview
The REF43GS-REEL, produced by Analog Devices Inc., is a low-power precision voltage reference that provides a stable +2.5V output. This component is designed to maintain its output voltage independent of variations in supply voltage, load conditions, or ambient temperature. It is particularly suitable for use in 8-, 10-, and 12-bit data acquisition systems, as well as any application requiring a stable, known voltage reference.
The REF43GS-REEL features tight output tolerances and low thermal drift, achieved through zener-zap trimming of both the output voltage and its temperature coefficient. A unique curvature correction circuit reduces the thermal curvature characteristic of many previous bandgap references, ensuring high precision and stability.
