Working Principles

The ADV3228ACPZ is an analog-to-digital converter that converts continuous analog signals into discrete digital values. It utilizes a successive approximation register (SAR) architecture to achieve high-speed and precise conversion. The analog input voltage is sampled at a rate of 1 MSPS and compared to the internal reference voltage. The SAR algorithm iteratively approximates the input voltage by adjusting the digital output until it matches the analog input within the desired resolution.
