Working Principles

The MAX1181ECM+TD is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a combination of sample-and-hold circuitry, quantization, and encoding techniques to achieve this conversion. The analog input signal is sampled at a specific rate and held during the conversion process. The sampled voltage is then quantized into a digital value using the 18-bit resolution of the ADC. Finally, the digital data is encoded and outputted for further processing or storage.
