Working Principles

The MAX1270BCNG is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation algorithm to determine the digital representation of the input voltage. The input voltage is sampled and held, and the internal ADC circuitry compares it with a reference voltage. By iteratively adjusting the comparison, the ADC converges on the digital code that best represents the input voltage.
