Working Principles

The MAX1248AEEE is an analog-to-digital converter that converts continuous analog signals into discrete digital values. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The input analog signal is sampled and held, and the ADC iteratively approximates the digital value by comparing the held voltage with a binary-weighted reference voltage. The conversion process is controlled by an internal clock and serial interface.
