Working Principles

TLV0838CPWG4 operates on the principle of successive approximation. It uses an internal digital-to-analog converter (DAC) and a comparator to iteratively approximate the input analog voltage. The ADC compares the input voltage with the DAC's output and adjusts the DAC's value until the two voltages match within the desired accuracy. This process repeats for each bit of the conversion, resulting in an 8-bit digital representation of the input voltage.
