ADR441BRZ

The ADR441BRZ is a type of XFET voltage references featuring ultralow noise, high accuracy, and low temperature drift performance. Using analog ADR441BRZ devices, Inc, patented temperature drift curvature correction and XFET (eXtra implan ted junction FET) technology, voltage change vs. temperature nonlinearity in the ADR44x is greatly minimized.The XF ET references provide better noise performance than buried Zener references, and XFET references operate off low supply voltage headroom (0.5 V). This integration of features makes the ADR44x family ideal for precision signal conv ersion applications in high-end data acquisition systems, optical networks, and medical applications.

Features of the ADR441BRZ are:(1)ultralow noise is 1.2 V p-p;(2)superb temperature coefficient of A grade is 10 pp m/°C;(3)low dropout operation is 500 mV;(4)input range is (VOUT + 500 mV) to 18 V;(5)high output source and sink current is +10 mA and -5 mA;(6)wide temperature ranges from -40°C to +125°C.
