    4044The LM83 is a digital temperature sensor. It senses its own temperature as 
    41 well as the temperature of up to three external diodes. It is compatible 
    42 with many other devices such as the LM84 and all other ADM1021 clones. 
    43 The main difference between the LM83 and the LM84 in that the later can 
    44 only sense the temperature of one external diode.
