75˚C Accurate, Remote Diode and Local Digital Temperature Sensor with Two-Wire Interface December 2004 LM89 ± 0.
75˚C Accurate, Remote Diode and Local Digital Temperature Sensor with Two-Wire Interface General Description The LM89 is an 11-bit digital temperature sensor with a 2-wire System Management Bus (SMBus) serial interface.
The LM89 accurately measures its own temperature as well as the temperature of an external device, such as processor thermal diode or diode-connected transistor such as the 2N3904.
The temperature of any ASIC can be accurately determined using the LM89 as long as a dedicated diode (semiconductor junction) is available on the target die.
The LM89 remote se...
