Working Principles
The AD574AUD utilizes the SAR architecture to convert analog signals into digital data. It samples the input voltage, holds it using a sample-and-hold circuit, and compares it with a reference voltage. The converter then successively approximates the digital value by adjusting the comparison voltage until it matches the input voltage within the desired resolution.
