Working Principles

The ADS8331IBPW operates by sampling the analog input voltage and converting it into a digital representation. It uses a successive approximation register (SAR) architecture combined with an internal reference voltage generator. The analog input voltage is compared to a series of voltage levels generated by the SAR, and the digital output is determined based on these comparisons.
