Working Principles

The ADS8484IRGZR 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 against a reference voltage using a binary search algorithm. The conversion result is then outputted in serial format through the data output pin.
