LM89 Remote Diode And Local Digital Temperature Sensor

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 diodeconnected transistor such as the 2N3904. The tempe.
