Working Principles

The MAX3186CWP+T is an analog front-end IC designed for temperature measurement. It utilizes a differential input architecture to accurately sense the temperature difference between two inputs (AIN+ and AIN-). The analog voltage output is then converted into digital data using an internal ADC (Analog-to-Digital Converter) and transmitted through the SPI interface.
