29Description
30-----------
31
32The ADM1030 and ADM1031 are digital temperature sensors and fan controllers.
33They sense their own temperature as well as the temperature of up to one
34(ADM1030) or two (ADM1031) external diodes.
35
36All temperature values are given in degrees Celsius. Resolution is 0.5
37degree for the local temperature, 0.125 degree for the remote temperatures.
38
39Each temperature channel has its own high and low limits, plus a critical
40limit.
41
42The ADM1030 monitors a single fan speed, while the ADM1031 monitors up to
43two. Each fan channel has its own low speed limit.
