Working Principles

The ADS8484IBRGZT is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation register (SAR) architecture combined with an internal reference voltage to achieve high-resolution conversion. The analog input voltage is sampled and quantized into a 16-bit digital value using a comparator and a digital-to-analog converter (DAC). The converted digital data is then transmitted through the serial interface for further processing or storage.
