Working Principles

The MAX1406EWE is an analog-to-digital converter that converts continuous analog signals into discrete digital values. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The input analog signal is sampled and held, and the internal ADC circuitry compares the sampled voltage with a reference voltage. By iteratively adjusting the comparison voltage, the ADC determines the digital representation of the input signal.
