Working Principles

The ADS8318IDGST is based on the successive approximation register (SAR) architecture. It utilizes a capacitor array and a comparator to perform the analog-to-digital conversion. The input voltage is sampled and compared against a reference voltage, with the converter iteratively adjusting the digital representation until it converges to the closest value.
