Working Principles

The MAX192ACAP+T is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input signal is compared to a reference voltage, and the converter determines the digital representation based on the comparison result. The converted digital data is then transmitted through the serial interface for further processing.
