UL recognised (LM75B)

The Texas Instruments digital temperature sensors comes with an integrated Sigma-Delta analog-to-digital converter and I2C interface. It provides 9-bit digital temperature readings with an accuracy of ±2°C from -25°C to 100°C and ±3°C over –55°C to 125°C. Communication is accomplished over a 2-wire interface which operates up to 400kHz.

No External Components Required
Shutdown Mode to Minimize Power Consumption
Up to Eight LM75s Can be Connected to a Single Bus
Power Up Defaults Permit Stand-alone Operation as Thermostat
