Working Principles

The MAX1241CEPA is an analog-to-digital converter that converts continuous analog signals into discrete digital values. It utilizes a successive approximation algorithm to determine the digital representation of the input voltage. The analog signal is sampled and held, and then the internal ADC circuitry compares the held voltage with a reference voltage. By iteratively adjusting the comparison value, the ADC converges on the digital output corresponding to the input voltage.
