Working Principles

The AD5675ARUZ operates by sampling an analog input signal and converting it into a digital representation. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input voltage is compared to a reference voltage, and the converter determines the digital code that best represents the input voltage. This digital code is then output through the serial interface.
