Working Principles

The LTC1290CISW#PBF is an analog-to-digital converter that converts continuous analog signals into discrete digital values. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversions. The input voltage is sampled and compared against an internal reference voltage, and the conversion process iteratively approximates the input voltage until the digital output is obtained.
