Working Principles

The TLV2543CDBRG4 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 sampled and compared against a reference voltage. The converter iteratively adjusts the digital output bits until the digital representation closely matches the input voltage. The resulting digital data can then be processed by a microcontroller or other digital system.
