Working Principles
The MAX1248ACEE+T 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 analog input is sampled at a high rate, and the internal ADC compares the input voltage against a reference voltage. By iteratively adjusting the digital code, the ADC converges towards the closest digital representation of the analog input.
