Working Principles

The MAX1420ECM+T is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The input analog voltage is sampled and held, and then compared to a reference voltage. The converter iteratively approximates the input voltage by adjusting the digital code until the best match is achieved. The resulting digital output represents the converted value of the input analog signal.
