Overview
The MAX1363EUB+T, produced by Analog Devices Inc./Maxim Integrated, is a low-power, 12-bit, 4-channel analog-to-digital converter (ADC) designed for system monitoring applications. This device features a digitally programmable window comparator with an interrupt output, enabling automatic system monitoring without host interaction. It integrates an internal voltage reference, a clock, and a high-speed I²C-compatible 2-wire serial interface. The MAX1363EUB+T is particularly suited for applications requiring precise and efficient analog-to-digital conversion, such as in servers, workstations, and high-reliability power supplies.
