Working Principles

The TLV2556IPW 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-speed and accurate conversions. The input analog voltage is compared against a reference voltage, and the converter determines the digital representation by iteratively adjusting the comparison value. The converted digital data is then transmitted through the SPI interface for further processing or storage.
