Working Principles

The ADS7279IPWR 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 signal is sampled and held, and the internal SAR circuitry compares the input voltage with a reference voltage. By iteratively adjusting the digital code, the converter determines the closest digital representation of the analog input. The resulting digital data is then outputted through the serial interface.
