Working Principles

The TLC2555IDGKG4 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 compared against an internal reference voltage, and the converter determines the digital representation based on this comparison. The clock input controls the sampling rate, and the chip select input enables or disables the conversion process. The digital output provides the converted data in a serial format.
