Working Principles

The MAX118EAI+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 voltage is compared against a reference voltage, and the converter determines the digital code that best represents the input voltage.

The conversion process involves sampling the analog input, holding the sample, and sequentially comparing it bit by bit until the digital output is obtained. The converted digital data can then be processed and utilized by microcontrollers or other digital systems.
