Description
The device can be used as a stand-alone temperature controller at power-up;
Separate Open-Drain OS Output Operates as Interrupt or Comparator/Thermostat Input
Register Readback Capability
Power-Up Defaults Permit Stand-Alone Operation as a Thermostat
Low Operating Supply Current 250µA (typ), 1mA (max)
4µA (typ) Shutdown Mode Minimizes Power Consumption
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 read directly from the I2C bus.
The data in the internal registers and the four data registers can be operated by I2C to set different operating modes.
The LM75A has three optional logical address pins, so that 8 devices can be connected simultaneously on the same bus without An address conflict has occurred.
