Working Principles

The TLC4501IDR 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 input analog voltage is compared against the internal reference voltage using a comparator, and the SAR iteratively approximates the digital representation of the input voltage. The resulting digital output is then transmitted serially through the SDATA pin.
