Working Principles

The AD7693BCPZRL is based on the successive approximation register (SAR) architecture. It utilizes a capacitor array and a comparator to perform the analog-to-digital conversion. The input voltage is sampled and held by the internal sample-and-hold circuitry. The SAR algorithm then determines the digital representation of the input voltage by comparing it to a series of reference voltages. The resulting digital code is output through the serial interface.
