Overview
The REF43GSZ-REEL7 is a low power precision voltage reference IC produced by Analog Devices Inc. This component provides a stable 2.5V output that is independent of variations in supply voltage, load conditions, or ambient temperature. It is particularly suitable as a reference level for 8-, 10-, and 12-bit data acquisition systems, or in any application where a stable, known voltage is required. The REF43 series utilizes zener-zap trimming to ensure tight output tolerances and low thermal drift, and a unique curvature correction circuit to reduce thermal curvature characteristic of many previous bandgap references.
