Overview
The MAX1364EUB+, 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 supports SMBus alert responses, allowing quick identification of the alarming device on a shared interrupt.
The MAX1364EUB+ integrates an internal voltage reference, a clock, and a high-speed, I²C-compatible, 2-wire serial interface. It operates from a single 4.5V to 5.5V supply and includes power-saving features such as AutoShutdown, which reduces supply current to less than 1µA when idle.
