Working Principles

The MAX1270ACNG+ operates based on the successive approximation register (SAR) architecture. It utilizes a capacitor array and a comparator to perform the analog-to-digital conversion process. The input analog signal is sampled, held, and compared against a reference voltage. The comparator generates a binary code that represents the input voltage level, which is then converted into digital data using the SAR algorithm.
