Working Principles

The MAX4080TASA-T operates based on the principle of measuring the voltage drop across a sense resistor to determine the current flowing through it. The differential inputs (IN+ and IN-) sense the voltage across the sense resistor, which is then amplified and converted into an output voltage proportional to the current being measured. This output voltage can be further processed or monitored as required.
