Working Principles

The AD7952BSTZ is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The input voltage is sampled, quantized, and converted into a binary representation using internal circuitry. The digital output is then transmitted through a serial interface for further processing or storage.
