Working Principles

The MAX11123ATI+ operates by converting analog input voltages into digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input voltage is compared to a reference voltage, and the ADC iteratively approximates the input voltage until a digital representation is obtained. The converted digital data can then be processed and analyzed by an external microcontroller or digital system.
