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.
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.
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.
