Working Principles

The MAX127ACAI+G002 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 the internal SAR circuitry compares the sampled voltage with a reference voltage. By iteratively adjusting the digital code, the converter determines the closest digital representation of the input voltage.
