LM75  
Digital Temperature Sensor and Thermal Watchdog with  
Two-Wire Interface  
General Description  
The LM75A, LM75B and LM75C are a family of industy-stan-  
dard digital temperature sensors with an integrated Sigma-  
Delta analog-to-digital converter and I2C® interface. The  
LM75 provides 9-bit digital temperature readings with an ac-  
curacy of ±2°C from -25°C to 100°C and ±3°C over -55°C to  
125°C.  
General System Thermal Management  
Features  
The LM75A operates with a single supply from +2.7V to  
+5.5V. Communication is accomplished over a 2-wire inter-  
face which operates up to 400kHz. The LM75 has three  
address pins, allowing up to eight LM75 devices to operate  
on the same 2-wire bus. The LM75 has a dedicated over-  
temperature output (O.S.) with programmable limit and hys-  
tersis. 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.  
No external components required  
Shutdown mode to minimize power consumption  
Up to eight LM75s can be connected to a single bus  
Power up defaults permit stand-alone operation as  
thermostat  
UL Recognized Component (LM75B and LM75C)  
The wide temperature and supply range and I2C interface  
make the LM75 ideal for a number of applications including  
base stations, electronic test equipment, office electronics,  
personal computers, and any other system where thermal  
management is critical to performance. The LM75A, LM75B  
and LM75C are available in an SOP-8 pacakage. The LM75B  
and LM75C are available in an MSOP-8 package.
