Product Overview

The MCP9800/1/2/3 family of digital temperature sensors from Microchip Technology Inc. offers precise temperature monitoring with a 12-bit resolution and accuracy up to 0.5C (typical at +25C). These sensors convert temperatures between -55C and +125C into a digital word, featuring user-selectable resolution from 9-12 bits. They operate on a wide voltage range (2.7V to 5.5V) and utilize a 2-wire I2C/SMBus compatible interface. With low operating current (200 A typical) and power-saving modes like Shutdown and One-shot, they are ideal for various applications including personal computers, servers, entertainment systems, and mobile phones, particularly for sophisticated multi-zone temperature monitoring.
