Working Principles

The TLC1078IDG4 is an 8-bit analog-to-digital converter that converts continuous analog signals into discrete digital values. It utilizes a successive approximation register (SAR) architecture to perform the conversion. The analog input voltage is compared against a reference voltage, and the converter determines the digital code that best represents the input voltage. The converted digital data is then transmitted through the serial interface for further processing or storage.
