Working Principles

The ADS8345NB/1KG4 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 analog input voltage is compared against an internal reference voltage, and the converter iteratively approximates the input value until the digital output converges to the correct representation.
