Working Principles

The MAX1204BEPP 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 signal is sampled and held, and the ADC compares the sampled voltage with a reference voltage. By iteratively adjusting the comparison voltage, the ADC determines the digital representation of the input signal.
