It is a high-speed I2C interface temperature sensor. In the temperature range of -55 ℃ ~ + 125 ℃, the temperature was directly converted to digital signals, and to achieve the accuracy of 0.125 ℃. MCU can read data of its internal registers directly via I2C bus, and can operate four registers through I2C to set different operating modes. LM75A has three selectable logic address pins, making it possible to connect eight devices at the same time without address conflict on the same bus.

1. I2C bus interface, the device address 7 slave address 1001xxx, can expand external eight devices on the same bus;
2. Power range: 2.8V ~ 5.5V, temperature range: -55~+125'C;
3. 11bit ADC provides a temperature resolution of 0.125'C;
4. Temperature accuracy:±2'C(-25~100'C),±3 ℃(-55~125'C)
5. Programmable temperature threshold and hysteresis set points;
6. In order to reduce power consumption, the current consumption in shutdown mode is only 1.0uA;
7. On power-up the device can be used as a stand-alone temperature controller

ESD protection:
JESD22A114 standard: through 2000V HBM mode
JESD22A115 standard: through  200V MM mode
JESD22-C101 standard: through 1000V CDM mode
JEDEC (JESD78) standard: latch-up test can up to 100mA
