LM92
www.ti.com SNIS110D – MARCH 2000 – REVISED MARCH 2013 ±0.33°C Accurate, 12-Bit + Sign Temperature Sensor and Thermal Window Comparator
With Two-Wire Interface
Check for Samples: LM92 FEATURES DESCRIPTION The LM92 is a digital temperature sensor and thermal
window comparator with an I2Cв„ў Serial Bus interface
and an accuracy of В±0.33В°C. The window-comparator
architecture of the LM92 eases the design of
temperature control systems. The open-drain
Interrupt (INT) output becomes active whenever
temperature goes outside a programmable window,
while a separate Critical Temperature Alarm
(T_CRIT_A) output becomes active when the
temperature exceeds a programmable critical limit.
The INT output can operate in either a comparator or
event mode, while the T_CRIT_A output operates in
comparator mode only. 1 23 Window Comparison Simplifies Design of
