超低噪声XFET基准电压与电流库和源能力 Ultralow Noise XFET Voltage References with Current Sink and Source Capability
GENERAL DESCRIPTION
The ADR43x series is a family of XFET voltage references featuring low noise, high accuracy, and low temperature drift performance. Using ’s patented temperature drift curvature correction and XFET eXtra implanted junction FET technology, the ADR43x’s voltage change versus temperature nonlinearity is minimized.
