Working Principles

The MAX1204BEAP 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 analog voltage is sampled and held, and then the internal ADC circuitry compares it to a reference voltage. By iteratively adjusting the digital code, the ADC converges on the closest digital representation of the input voltage. This digital code is then output through the serial interface.
