REF43:  +2.5V Low Power Precision Voltage Reference

Product Details


The 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 12-bit data acuisition systems, or wherever a stable, know voltage is required.

Tight output tolerances and low thermal drift are assured by zener-zap trimming of both outout voltage and its temperature coefficient. A unique curvature correction circuit reduces the thermal curvature which is characteristic of many previous bandgap references.
