Working Principles

The TLV2543CDWR 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 a reference voltage, and the converter determines the digital code that best represents the input voltage.

The conversion process involves sampling the analog input, quantizing it into discrete levels, and encoding it into binary format. The TLV2543CDWR uses a 12-bit resolution, which means it can represent the analog input voltage with 2^12 (4096) different digital codes. The conversion is controlled by the serial clock (SCLK) and serial data input (SDI) signals.
