Working Principles

The TLV1572IDR is an analog-to-digital converter that operates based on the successive approximation technique. It converts continuous analog signals into discrete digital data by comparing the input voltage with a reference voltage and determining the closest digital representation.

The conversion process starts by applying the analog input voltage (AIN) to the ADC. The internal circuitry then compares this voltage with the reference voltage (VREF) using a binary search algorithm. By successively approximating the digital output, the ADC converges towards the most accurate representation of the analog input.
