Working Principles

The MAX106CHC-D 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 analog input voltage is sampled and held, and then the internal SAR circuitry compares it to a reference voltage. By iteratively adjusting the digital code, the converter determines the closest digital representation of the analog input.
