LM82 Remote Diode and Local Digital Temperature Sensor

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 DeltaSigma analog-to-digital converter with a digital overtemperature detector. The LM82 accurately senses its own temperature as well as the temperature.
