The LM75A 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 LM75A operates with a single supply from +2.7 V to +5.5 V. Communication is accomplished over a 2-wire interface which operates up to 400kHz. +The LM75A has three address pins, allowing up to eight LM75A devices to operate on the same 2-wire bus. The LM75A has a dedicated over-temperature output (O.S.) with +programmable limit and hysteresis. 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. + + ```text -address: 0x4B +address: 0x49 ``` ### I2C Air Temperature, Pressure and Humidity Sensor Board (BME280)
