Working Principles

The AD7111LNZ 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-speed and accurate conversion. The analog input voltage is compared to the reference voltage, and the converter determines the digital representation by iteratively approximating the input voltage. The resulting digital data is then outputted serially.
