Working Principles

The TLV1572CDRG4 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 conversion. The input voltage is sampled and compared against a reference voltage using a comparator. The SAR then iteratively approximates the digital representation of the input voltage by adjusting the most significant bit (MSB) based on the comparison result. This process continues until the entire 12-bit resolution is obtained.
