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