The LM99 is an 11-bit remote diode temperature sensor with a 2-wire System Management Bus (SMBus) serial interface.
The LM99 accurately measures: (1) its own temperature and (2) the temperature of a remote diode-connected transistor such as the 2N3904 or a thermal diode commonly found on Graphics Processor Units (GPU), Computer Processor Units (CPU or other ASICs.
The LM99 remote diode temperature sensor shifts the temperature from the remote sensor down 16˚C and operates on that shifted temperature: TACTUAL DIODE JUNCTION = TLM99 + 16˚C The local temperature reading requires no offset.
LM99 ± 1˚C Accurate, High Temperature, Remote Diode Temperature Sensor with Two-Wire Interface July 2003 LM99 ± 1˚C Accurate, High Temperature, Remote Diode Temperature Sensor with Two-Wire.
