The ADR290, ADR291 and ADR292 are low noise, micro power precision voltage references that use an XFET®reference circuit. The new XFET architecture offers significant performance improvements over traditional bandgap and Buried Zener-based references. Improvements include: one quarter the voltage noise output of bandgap references operating at the same current, very low and ultralinear temperature drift, low thermal hysteresis and excellent long-term stability.
