Working Principles

The ISO124U/1K is an isolation amplifier that utilizes a differential input stage to provide galvanic isolation between the input and output signals. It amplifies the differential voltage between the IN+ and IN- pins while rejecting common-mode noise. The amplified signal is then available at the OUT pin, which can be further processed or transmitted.
