Overview
The ADR420BRZ-REEL7 from Analog Devices Inc. is an ultraprecision, low noise voltage reference IC. It features Analog Devices' second-generation eXtra implanted junction FET (XFET) technology, which provides low noise, high accuracy, and excellent long-term stability. The device incorporates 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.
