Overview
The ADR423ARZ is an ultraprecision, low-noise voltage reference produced by Analog Devices Inc. This second-generation device utilizes extra implanted junction FET (XFET) technology, which ensures high accuracy, low noise, and excellent long-term stability. The ADR423ARZ features a patented temperature drift curvature correction technique, minimizing the nonlinearity of the voltage change with temperature. This makes it superior to traditional band gap references in terms of accuracy and thermal hysteresis.
