Working Principles

The MAX1081BEUP+T is an 8-bit ADC that converts analog signals into digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-speed and accurate conversion. The analog input signal is sampled and held, then compared to a reference voltage. The comparator determines the most significant bit (MSB) by comparing the input voltage with the midpoint of the reference voltage range. This process is repeated for each subsequent bit until the least significant bit (LSB) is determined. The resulting digital data is then available at the output pins.
