Working Principles

The PT8A3285BWEX 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 against the internal reference voltage, and the converter iteratively approximates the digital representation by adjusting the most significant bit (MSB) based on the comparison result. This process continues until the desired resolution is achieved.
