Working Principles

The LTC1408IUH#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-resolution conversion. The input voltage is sampled and compared against an internal reference voltage using a comparator. The SAR then iteratively approximates the input voltage by successively adjusting the digital code until it matches the input voltage within the desired accuracy. The resulting digital code is then output through the serial interface.
