Overview
The REF43GS-REEL7 is a +2.5V low power precision voltage reference 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.
