Working Principles

The ADS7851IRTET 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 to an internal reference voltage, and the converter determines the digital representation by successively approximating the input voltage. The converted digital data is then transmitted through the serial interface for further processing.
