Working Principles

The TLC2543IDWR 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 compared to a reference voltage, and the converter determines the digital code that best represents the input voltage.

The conversion process involves a series of comparisons and adjustments until the digital output accurately reflects the analog input. The resulting digital data can then be processed by a microcontroller or other digital system.
