Working Principles

The TLC1543QDWG4 operates on the principle of successive approximation. It uses a capacitor-based sample-and-hold circuit to capture the analog input voltage, which is then converted into a digital value using an internal 10-bit successive approximation register (SAR). The conversion process involves comparing the input voltage with a reference voltage and iteratively adjusting the digital output until it closely matches the input voltage.
