Working Principles

The AD585SQ is based on the successive approximation register (SAR) architecture. It utilizes a capacitor array and a comparator to perform the conversion process. The analog input signal is sampled and held, and then compared to a reference voltage using the internal comparator. The SAR algorithm iteratively determines the digital code that best represents the input signal. The resulting digital output is then available for further processing or storage.
