LM75B

LM75C Digital Temperature Sensor and Thermal Watchdog with Two-Wire Interface

Check for Samples: LM75B, LM75C

FEATURES

DESCRIPTION

The LM75B and LM75C are industy-standard 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 accuracy of ±2°C from -25°C to 100°C and ±3°C

over -55°C to 125°C.

•

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

Communication is accomplished over

a 2-wire

interface 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 hystersis. 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 LM75B and LM75C are

available in an SOIC package or VSSOP package.
