Product Descriptions

The REF-43 is a low-power precision reference providing astable +2.5V output independent of variations in supply voltage,load conditions or ambient temperature. It is suitable as areference level for 8, 10 and 12-bit data acquisition systems, orwherever a stable, known voltage is required.

Tight output tolerances and low thermal drift are assured byzener-zap trimming of both output voltage and its temperaturecoefficient. A unique curvature correction circuit reduces thethermal curvature which is characteristic of many previousbandgap references.
