1 Introduction

Several automotive systems and industrial systems operate at high voltages in harsh environments, making high-performance isolated voltage sensing designs critical for maintaining system efficiency and long-term reliability. Selecting the correct isolated amplifier requires many considerations, such as system accuracy, PCB space, and cost for the system that the device is being implemented into. To design systems with improved accuracy at a reduced design size and cost, while still meeting performance requirements, Texas Instruments introduces the AMC0xxxD/S/R product family, a new portfolio of isolated AC and DC voltage sensing amplifiers with options of a differential output, single-ended fixed gain and ratiometric output.
