Microchip’s MCP9801 is a digital temperature sensor designed for applications requiring high accuracy and flexibility. It converts temperatures between -55°C and +125°C into a digital word, offering accuracy of ±1°C (maximum) from -10°C to +85°C. The sensor features user-programmable registers for temperature measurement resolution, shutdown modes, and alert output configuration. Its industry-standard 2-wire I2C/SMBus interface enables control of multiple devices on a single serial bus, making it suitable for sophisticated multi-zone temperature monitoring in personal computers, servers, and other industrial applications.
