Overview
The ADR293GRZ-REEL7 is a low noise, micropower precision voltage reference IC produced by Analog Devices Inc. This device is part of the Power Management (PMIC) segment of Integrated Circuits (ICs) and utilizes an XFET® (eXtra implanted junction FET) reference circuit. The XFET architecture provides significant performance improvements over traditional band gap and buried Zener-based references, including lower voltage noise, very low and ultralinear temperature drift, low thermal hysteresis, and excellent long-term stability.
