Working Principles

The ADV3227ACPZ is an analog-to-digital converter (ADC) that converts continuous analog signals into discrete digital values. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input voltage is sampled at a fast rate using an internal sample-and-hold circuit. The sampled voltage is then compared to a reference voltage, and the SAR algorithm determines the digital code that represents the input voltage. The digital output is provided in serial format.
