Working Principles

The AD21478WYSWZ2A02 is an analog-to-digital converter (ADC) that converts continuous analog signals into discrete digital values. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input voltage is compared to a reference voltage, and the ADC determines the digital representation based on this comparison. The conversion process is controlled by the clock input and can be initiated through the chip select input. The converted digital data is then transmitted through the serial data output pin.
