Datasheet Summary
ACPI‐pliant, High
Accuracy Microprocessor
System Temperature Monitor
The ADM1023 is a 2-channel digital thermometer and under/overtemperature alarm for use in personal puters and other systems requiring thermal monitoring and management. Optimized for the Pentium III, the higher accuracy allows systems designers to safely reduce temperature guard banding and increase system performance. The device can measure the temperature of a microprocessor using a diode-connected PNP transistor, which may be provided on-chip with the Pentium III or similar processors; or it can be a low-cost, discrete NPN/PNP device such as the 2N3904/2N3906. A novel measurement technique cancels out...
