21 | The LM83 is a digital temperature sensor. It senses its own temperature as | |
43cb7ebe JC |
22 | well as the temperature of up to three external diodes. The LM82 is |
23 | a stripped down version of the LM83 that only supports one external diode. | |
24 | Both are compatible with many other devices such as the LM84 and all | |
25 | other ADM1021 clones. The main difference between the LM83 and the LM84 | |
26 | in that the later can only sense the temperature of one external diode. | |

28 | Using the adm1021 driver for a LM83 should work, but only two temperatures | |
29 | will be reported instead of four. | |

31 | The LM83 is only found on a handful of motherboards. Both a confirmed | |
32 | list and an unconfirmed list follow. If you can confirm or infirm the | |
33 | fact that any of these motherboards do actually have an LM83, please | |
34 | contact us. Note that the LM90 can easily be misdetected as a LM83. | |

45 | The LM82 is confirmed to have been found on most AMD Geode reference |
46 | designs and test platforms. | |
