Working Principles

The AD9240ASZRL utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It samples the analog input voltage at a high rate and compares it with a reference voltage. The converter then generates a digital code that represents the input voltage. This process is repeated for each sample, resulting in a stream of digital data.
