Working Principles

The TLC3544IPWR is an analog-to-digital converter that converts analog signals into digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The input analog signal is compared to a reference voltage, and the converter determines the digital representation based on this comparison. The digital output is then transmitted through the serial interface.
