Product Overview

The LM75A/B/C is an industrial-standard digital temperature sensor and thermal monitor designed for general system thermal management. It offers precise temperature measurement with an error of less than 1C across a wide operating range of -40C to +125C. Featuring a dual-wire interface (I²C compatible), it supports connecting up to eight devices on a single bus. The LM75 is ideal for applications requiring accurate thermal monitoring and protection, such as communication infrastructure, electronic test equipment, and environmental monitoring. Its programmable temperature limits and ALERT pin allow it to function as a thermostat or over-temperature alarm. The device operates from a single +2.7V to +5.5V supply and requires no external components.
