Working Principles

The TLC254CD 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 input analog signal is sampled and held, and then the internal SAR circuitry compares the sampled voltage with a reference voltage. By iteratively adjusting the digital code, the converter determines the digital representation of the input signal.
