Working Principles

The AD5570ARS utilizes a successive approximation register (SAR) architecture for analog-to-digital conversion. The analog input signal is sampled and held, and then a binary search algorithm is employed to determine the digital representation of the input voltage. The internal reference voltage is used as a comparison point during the conversion process. The converted digital data is then output through the serial interface.
