Analog Devices ADM1031
The ADM1031 is an ACPI-compliant three-channel digital thermometer and under/over temperature alarm, for use in personal computers and thermal management systems. Optimized for the Pentium III, the higher 1°C accuracy offered allows systems designers to safely reduce temperature guardbanding and increase system performance. The speed of each fan can be monitored via TACH inputs.| Part No. | ADM1031 |
