Working Principles

The AD7667ACPZRL utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It samples the analog input voltage, compares it to a reference voltage, and iteratively determines the digital representation by adjusting the bits in the SAR. The conversion process is controlled by an internal clock and can be initiated by a convert start signal.
