30*4882a593Smuzhiyun-----------
31*4882a593Smuzhiyun
32*4882a593SmuzhiyunThe ADM1030 and ADM1031 are digital temperature sensors and fan controllers.
33*4882a593SmuzhiyunThey sense their own temperature as well as the temperature of up to one
34*4882a593Smuzhiyun(ADM1030) or two (ADM1031) external diodes.
35*4882a593Smuzhiyun
36*4882a593SmuzhiyunAll temperature values are given in degrees Celsius. Resolution is 0.5
37*4882a593Smuzhiyundegree for the local temperature, 0.125 degree for the remote temperatures.
38*4882a593Smuzhiyun
39*4882a593SmuzhiyunEach temperature channel has its own high and low limits, plus a critical
40*4882a593Smuzhiyunlimit.
41*4882a593Smuzhiyun
42*4882a593SmuzhiyunThe ADM1030 monitors a single fan speed, while the ADM1031 monitors up to
43*4882a593Smuzhiyuntwo. Each fan channel has its own low speed limit.
