LM76
Description
The LM76 is a digital temperature sensor and thermal window parator 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. The window-parator architecture of the LM76 eases the design of temperature control systems conforming to the ACPI (Advanced Configuration and Power Interface) specification for personal puters. The open-drain Interrupt (INT) output bees active whenever temperature goes outside a programmable window, while a separate Critical Temperature Alarm (T_CRIT_A) output bees active when the temperature exceeds a programmable critical limit. The INT output can operate in either a parator or event mode, while the T_CRIT_A output operates in parator mode only. The host can program both the upper and lower limits of the window as well as the critical...
