Overview
The ADR420ARM-REEL7 is a part of the ADR42x series of ultraprecision voltage references produced by Analog Devices, Inc. These devices are known for their high accuracy, low noise, and excellent long-term stability. The ADR420ARM-REEL7 specifically provides a fixed output voltage of 2.048V and is designed using the second-generation eXtra implanted junction FET (XFET) technology. This technology ensures superior accuracy and thermal hysteresis compared to traditional band gap references and operates at lower power and supply headroom than buried Zener references.
