Working Principles

The MAX120EAG 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 sampled, quantized, and converted into a binary representation using a comparator and a digital-to-analog converter (DAC). The converted digital data can then be processed by a microcontroller or other digital devices.
