Working Principles

The TLV2548CPWG4 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 sampled and held, and then the internal SAR circuitry compares it to a reference voltage. By iteratively adjusting the digital code, the converter determines the closest digital representation of the analog input. The converted digital data is then made available through the serial interface.
