Working Principles

The MAX1245AEPP 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 ADC operates by comparing the input voltage with a reference voltage and generating a binary output based on the comparison result. The resolution of 12 bits allows for a finer digital representation, resulting in more accurate measurements.
