Analog Devices ADM1030
The ADM1030 is an ACPI-compliant two-channel digital thermometer and under/over temperature alarm, for use in 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 the fan can be monitored via a TACH input for a fan with a tach output.| Part No. | ADM1030 |
