Product Summary
The ADR291ERZ is a low noise, micropower precision voltage reference 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. The ADR291ERZ provides stable and accurate output voltages options are 2.5V. The applications of the ADR291ERZ include Portable Instrumentation, Precision Reference for 3V and 5V Systems, A/D and D/A Converter Reference, Solar-Powered Applications, Loop-Current-Powered Instruments.
