Working Principles

The MAX1407EAI+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 sampled and held, and then the internal ADC core compares it to a reference voltage. The conversion process iteratively approximates the input voltage until the digital output code is obtained.
