Working Principles

TLV1549IDR utilizes successive approximation register (SAR) architecture to convert analog signals into digital data. It employs a comparator, a digital-to-analog converter (DAC), and a control logic circuit to iteratively approximate the input voltage and determine the corresponding digital output.

The conversion process involves comparing the input voltage with the DAC's output voltage and adjusting the DAC's value until the two voltages match within the desired accuracy. This iterative process continues until the conversion is complete, resulting in a digital representation of the input voltage.
