Texas Instruments LM75B
The LM75B and LM75C are industry-standard digital temperature sensors with an integrated Sigma-Delta analog-to-digital converter and I2C interface. The LM75 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. The LM75 has three address pins, allowing up to eight LM75 devices to operate on the same 2-wire bus.| Part No. | LM75B |

DESCRIPTION
Communication is accomplished over a 2-wire interface which operates up to 400kHz. The LM75 has a dedicated over-temperature output (O.S.) with programmable limit and hystersis. This output has programmable fault tolerance, which allows the user to define the number of consecutive error conditions that must occur before O.S. is activated. The wide temperature and s...
