Overview
The ADR420ARMZ-REEL7 is a part of the ADR42x series of ultraprecision, second-generation eXtra implanted junction FET (XFET) voltage references produced by Analog Devices Inc. These devices are renowned for their low noise, high accuracy, and excellent long-term stability. The ADR420ARMZ-REEL7 specifically offers a 2.048V output voltage and is packaged in an 8-lead MSOP footprint, which is 30% smaller than the SOIC package, making it ideal for space-constrained applications.
