Working Principles

The TLC2543MDBREP operates based on the successive approximation method. It samples the analog input voltage and compares it with a reference voltage. The converter then generates a digital output code that represents the input voltage's magnitude.

The device utilizes an internal clock to control the conversion process. The analog input voltage is sampled and held, and the successive approximation register (SAR) performs a binary search to determine the digital code that best matches the input voltage. This process is repeated for each conversion cycle.
