ADR292GBC中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

The ADR290, ADR291 and ADR292 are low noise, micropower precision voltage references that use an XFET™ reference circuit. The new XFET architecture offers significant performance improvements over traditional bandgap and 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.
