Working Principles

The LTC1861IS8#TRPBF is a high-speed, low-power ADC that converts analog signals into digital data. It utilizes a successive approximation technique to determine the digital representation of the input voltage. The analog input signal is compared to the internal reference voltage, and the conversion process iteratively approximates the input voltage by adjusting the digital output code. The converted digital data is then transmitted through the serial interface.
