Description
The LM75A or B is a high-speed I2C interface temperature sensor that converts temperature directly to digital signals from -55°C to +125°C and achieves an accuracy of 0.125°C. The MCU can directly read the data in its internal registers through the I2C bus, and can operate four data registers through I2C to set different operating modes. The LM75A has three selectable logic address pins that allow eight devices to be connected simultaneously on the same bus without address conflicts.
