The ADR291W is a low noise, micropower precision voltage reference that uses an XFET® reference circuit. The XFET architecture offers significant performance improvements over traditional band gap and buried Zener-based references. Improvements include one quarter of the current noise, higher output current, and higher temperature stability. The ADR291W is an ideal choice for automotive applications because of its wide supply range, low noise, and high output current.
The ADR291W is a low noise, micropower precision voltage reference that utilizes an XFET® reference circuit. It provides a stable 2.5V output voltage from supply voltages as low as 2.8V, making it ideal for battery-powered instrumentation. The device offers significant performance improvements over traditional band gap and buried Zener-based references, including very low voltage noise and ultralinear temperature drift.
