Working Principles
The MAX4378HAUD+T is a current sense amplifier that accurately measures current flowing through a shunt resistor. It amplifies the small voltage drop across the shunt resistor and provides an output proportional to the current being sensed. The device operates by comparing the voltage across the shunt resistor with an internal reference voltage, and amplifying the difference using a high-gain amplifier. The amplified signal is then available at the OUT pin for further processing.
