Working Principles

The MAX1293AEEG 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 input analog voltage is sampled, amplified, and compared against a reference voltage. The converter then iteratively approximates the digital representation of the input voltage until the desired resolution is achieved.
