Working Principles

The MAX1271BEAI 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 conversions. The input voltage is sampled and compared against an internal reference voltage. The converter then iteratively approximates the input voltage by successively narrowing down the possible values until the digital representation is obtained.
