Working Principles

The TLC0820AIN 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 sampled and held, and then compared to a reference voltage using a comparator. The converter iteratively adjusts the digital output based on the comparison result until the desired accuracy is achieved.
