Working Principles

The TLV2556IDWG4 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 signal is compared to a reference voltage, and the converter determines the digital code that best represents the input voltage. This digital code is then output through the serial interface.
