ADR291GRUZ-REEL7

ADR291 is a low noise, micropower precision voltage reference. It uses an XFET® reference circuit. The new XFET architecture offers significant performance improvements over traditional band gap and buried zener-based references. Improvements include one quarter the voltage noise output of band gap references operating at the same current, very low and ultra linear temperature drift, low thermal hysteresis, and excellent long-term stability. This voltage reference is widely used in application such as portable instrumentation, precision reference for 3V and 5V systems, analog-to-digital and digital-to-analog converter reference, solar-powered applications, loop-current-powered instruments etc.
