Working Principles

The ADS7882IPFBR 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 signal is sampled and compared against a reference voltage. The converter then iteratively approximates the input voltage by adjusting the digital code until it matches the analog input within the desired accuracy. The resulting digital data is then available for further processing.
