LM82 Remote Diode and Local Digital Temperature Sensor with Two-Wire Interface January 2000 LM82 Remote Diode and Local Digital Temperature Sensor with Two-Wire Interface General Description The LM82 is a digital temperature sensor with a 2 wire serial interface that senses the voltage and thus the temperature of a remote diode using a Delta-Sigma analog-to-digital converter with a digital over-temperature detector. The LM82 accurately senses its own temperature as well as the temperature of external devices, such as Pentium II ® Processors or diode connected 2N3904s. The temperature of any ASIC can be detected using the LM82 as long as a dedicated diode (semiconductor junction) is...
