Working Principles

The ADS8505IBDW 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 compared to a reference voltage, and the converter iteratively approximates the input voltage by adjusting the digital output code. This process continues until the desired level of accuracy is achieved.
