Working Principles

The TLC1549IPG4 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 an internal reference voltage, and the converter iteratively approximates the input voltage by adjusting the digital output code. This process continues until the conversion is complete, resulting in a digital representation of the analog input.
