Working Principles

The AD9058AJJ utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It employs a sample-and-hold circuit to capture the input voltage, followed by a comparator that compares the sampled voltage with a reference voltage. The SAR then iteratively determines the digital representation of the input voltage by adjusting the bits of the output code until the desired accuracy is achieved.
