Working Principles

The ADS41B49IRGZ25 is an analog-to-digital converter that operates based on the successive approximation register (SAR) architecture. It converts analog signals into digital data by comparing the input voltage against a reference voltage and iteratively approximating the digital representation. The device utilizes a high-speed sampling technique to capture the analog signal accurately and then performs the conversion process using internal circuitry.
