LM83 Triple-Diode Input and Local Digital Temperature Sensor with Two-Wire Interface November 1999 LM83 Triple-Diode Input and Local Digital Temperature Sensor with Two-Wire Interface General Description The LM83 is a digital temperature sensor with a 2 wire serial interface that senses the voltage and thus the temperature of three remote diodes using a Delta-Sigma analog-to-digital converter with a digital over-temperature detector. The LM83 accurately senses its own temperature as well as the temperature of three external devices, such as Pentium II ® Processors or diode connected 2N3904s. The temperature of any ASIC can be detected using the LM83 as long as a dedicated diode...
