LM76 Datasheet 12-Bit Sign Digital Temperature Sensor and Thermal Window Comparator

Manufacturer: National Semiconductor (now Texas Instruments)

General Description

The LM76 is a digital temperature sensor and thermal window comparator with an I2C™ Serial Bus interface with an accuracy of ± 1˚C.

This accuracy for the LM76CHM is specified for a −10˚C to 45˚C temperature range, while for the LM76CNM the temperature range is 70˚C to 100˚C.

The LM76CHM is specified with an accuracy ± 0.5˚C at 25˚C.
