Working Principles

The TLV2556MPWREPG4 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 input voltage is compared to an internal voltage reference, and the ADC iteratively approximates the input voltage by adjusting its internal digital-to-analog converter (DAC) until the best match is found. The resulting digital output represents the converted analog value.
