Working Principles

The MAX1178AEUP+ utilizes successive approximation register (SAR) architecture to convert analog signals into digital data. It employs an internal reference voltage and a sample-and-hold circuit to capture the analog input signal. The SAR algorithm then iteratively approximates the digital value by comparing the input signal with a series of voltage levels. The final digital output represents the closest approximation to the input signal within the specified resolution.
