Working Principles

The ADS8671IPWR operates by sampling the analog input voltage and converting it into a digital representation. It utilizes an internal successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input is compared to a reference voltage, and the ADC iteratively adjusts the digital output until the conversion is complete.
