Working Principles

The AD574AKE is an analog-to-digital converter that operates based on the successive approximation method. It converts continuous analog signals into discrete digital data by comparing the input voltage with a reference voltage and determining the closest digital representation.

The converter uses a built-in digital-to-analog converter (DAC) to generate the reference voltage, which is then compared with the input voltage using a comparator. The successive approximation register (SAR) iteratively adjusts the DAC output until the digital representation matches the input voltage within the desired resolution.
