Working Principles

The ADS8028IRTJR is a 12-bit ADC that converts analog signals into digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input voltage is compared to the internal reference voltage, and the converter determines the digital representation based on the comparison results. The conversion process is controlled by the clock input and the serial interface.
