Working Principles

The TLC541IFN is an analog-to-digital converter that operates based on the successive approximation method. It converts analog signals into digital data by comparing the input voltage with a reference voltage and determining the closest digital representation.

The IC utilizes an internal reference voltage to establish the conversion range. The input voltage is sampled and held, and the successive approximation register (SAR) iteratively approximates the digital value by comparing the input voltage with different voltage levels. This process continues until the digital output accurately represents the input voltage.
