M75a is a i2c interface, temperature sensor, in the temperature range -55 c ~ + 125c the temperature was directly converted to a digital signal, and can achieve accuracy of 0. 125 c. MCU can be read directly through the i2c bus data in its internal registers, and through i2c data register of the four operations to be set to different operating modes. Lm75a has three selectable logic address pins, making it possible to simultaneously connect eight devices on the same bus without address conflict. Features: I2c bus interface, the device address 7 slave address 1001xxx, can expand outside eight devices on the same bus power supply range: 2. 8v ~ 5. 5v temperature range: -55 c~ + 125 c 11 bit aDC provides a temperature resolution: 0. 125c temperature accuracy: ± 2 c (-25 c ~ 100 c).
