Working Principles

The TLV1549CD is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation algorithm to determine the digital representation of the input voltage. The analog input signal is compared to a reference voltage, and the converter iteratively adjusts its internal digital code until the output accurately represents the input voltage.
