Working Principles

The MAX1246AEEE 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 input signal is sampled and held, and the ADC iteratively approximates the input voltage by comparing it with a reference voltage. The conversion process continues until the digital output accurately represents the analog input.
