Working Principles

The MAX1434ECQ+TD 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 to a reference voltage, and the converter determines the digital representation by iteratively approximating the input voltage.
