LM75A  
Digital Temperature Sensor and Thermal Watchdog with  
Two-Wire Interface  
General Description  
Applications  
The LM75A is an industry-standard digital temperature sen-  
sor with an integrated Sigma-Delta analog-to-digital converter  
and I2C® interface. The LM75A provides 9-bit digital temper-  
ature readings with an accuracy of ±2°C from -25°C to 100°  
C and ±3°C over -55°C to 125°C.  
General System Thermal Management  
Communications Infrastructure  
Electronic Test Equipment  
Environmental Monitoring  
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 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 hys-  
teresis. 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.  
Features  
No external components required  
Shutdown mode to minimize power consumption  
Up to eight LM75As can be connected to a single bus  
Power up defaults permit stand-alone operation as  
thermostat  
Key Specifications  
The wide temperature and supply range and I2C interface  
make the LM75A 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 is avail-  
able in an SOP-8 package and an MSOP-8 package.
