Working Principles

The TLV2548IPW 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 analog input voltage is compared against the internal reference voltage, and the converter iteratively approximates the digital representation of the input signal until the desired accuracy is achieved.
