Overview
The REF43GSZ from Analog Devices Inc. is a low-power precision voltage reference IC designed to provide a stable +2.5V output. This component is independent of variations in supply voltage, load conditions, or ambient temperature, making it highly reliable for various applications. The REF43GSZ is part of the REF43 series, known for its 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 thermal curvature, enhancing its performance over traditional bandgap references.
