ANALOG DEVICES ADR293: Low Noise Micropower 5.0 V Precision Voltage Reference Data Sheet (Rev D 2011-05-06-)
The ADR293 is a low noise, micropower precision voltage reference utilizing an XFET (eXtra implanted junction FET) reference circuit. This architecture provides significant performance improvements over traditional band gap and buried Zener-based references, including one quarter the voltage noise output of band gap references operating at the same current.
