The ADM1023 is a 2âchannel digital thermometer and under/overtemperature alarm for use in personal computers 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 diodeâconnected PNP transistor, which may be provided onâchip with the Pentium III or similar processors; or it can be a lowâcost, discrete NPN/PNP device such as the 2N3904/2N3906.
