The LM86 is an 11-bit digital temperature sensor with a 2-wire System Management Bus (SMBus) serial
interface. The LM86 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 LM86 as long as a dedicated diode (semiconductor junction) is available on the target die.
