Working Principles

The AD7564BN operates by sampling the analog input voltage and converting it into a corresponding digital value. It utilizes an internal reference voltage and successive approximation register (SAR) architecture to achieve accurate conversion. The analog input is compared to the reference voltage, and the ADC progressively approximates the digital output until the conversion is complete.
