Working Principles

The TLC254ID is an analog-to-digital converter that utilizes a successive approximation register (SAR) architecture. It converts continuous analog signals into discrete digital data by comparing the input voltage to a reference voltage and determining the closest digital representation.

The device uses an internal reference voltage generator to establish the reference voltage range. The analog input signal is sampled and held, and the conversion process begins. The SAR algorithm progressively approximates the input voltage by successively comparing it with different voltage levels until the digital output accurately represents the analog input.
