Working Principles

The MAX1281BCUP is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation algorithm to achieve high-resolution conversion. The analog input voltage is compared to a reference voltage, and the converter determines the digital representation based on this comparison. The digital output is then provided through a serial interface.
