Working Principles

The AD7680ARMZ is based on the successive approximation register (SAR) architecture. It uses a binary search algorithm to determine the digital representation of the analog input voltage. The ADC samples the input voltage, compares it with a reference voltage, and iteratively adjusts the digital code until it converges to the closest representation of the input voltage. This process ensures accurate conversion with high resolution.
