Working Principles

The MAX1169CEUD+ is an analog-to-digital converter (ADC) that converts analog signals into digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The input signal is sampled and compared against a reference voltage, and the ADC iteratively adjusts the digital representation until it matches the input signal within the desired accuracy. The converted digital data is then made available through the SPI interface for further processing.
