Working Principles

The TLV2545CDGK is an analog-to-digital converter that converts analog signals into digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input signals are sampled and quantized into discrete digital values using a comparator and a digital-to-analog converter (DAC). The converted digital data is then transmitted through the serial interface for further processing or storage.
