Working Principles

The LTC1289CCSW#TRPBF 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-speed and accurate conversions. The analog input voltage is sampled and compared against the internal reference voltage. The converter iteratively approximates the input voltage by adjusting the digital code until it matches the analog input within the desired accuracy. The resulting digital output represents the converted value of the analog input.
