Working Principles

The TLC251CPG4 is an analog-to-digital converter that converts continuous analog signals into discrete digital values. It utilizes a successive approximation register (SAR) architecture to achieve 12-bit resolution. The analog input voltage is compared against an internal reference voltage, and the converter iteratively approximates the input voltage by adjusting the digital output. The conversion process is controlled by the serial interface, which communicates with an external microcontroller.
