ОписаниеThe REF43 is a low power precision reference providing a stable 2.5V output independent of variations in supply voltage, load conditions or ambient temperature. It is suitable as a reference level for 8-, 10- and 12Bit data acquisition systems, or wherever a stable, known voltage is required Tight output tolerances and low thermal drift are assured by zener-zap trimming of both output voltage and its temperature coefficient. A unique curvature correction circuit reduces the thermal curvature which is characteristic of many previous bandgap references.
