Working Principles

The ADS7040IDCUR is an analog-to-digital converter that converts continuous analog signals into discrete digital values. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The input voltage is sampled and compared against a reference voltage, and the converter iteratively approximates the digital value by adjusting the comparison level. The resulting digital output represents the closest approximation of the input voltage.
