Working Principles

The MAX1247ACPE 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 analog input signal is compared to a reference voltage, and the converter determines the digital code that best represents the input voltage. This process is repeated for each input channel, resulting in a digital output corresponding to the analog input.
