Abstract

This application report explores the benefits of using the latest generation of isolated amplifiers with single-ended output, specifically the ratiometric configuration (AMC0330R), which automatically adjusts gain to match the reference voltage. By leveraging this functionality, systems can enhance signal integrity and optimize analog-to-digital conversion chains.
