Working Principles

The AD1674BD utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It employs a capacitor-based digital-to-analog converter (DAC) and a comparator to perform the conversion process. The input voltage is sampled, quantized, and compared to the DAC output in a series of iterations until the digital representation reaches the desired accuracy.
