| PRODUCT DESCRIPTION The ADM1020 is a two-channel digital thermometer and under/over temperature alarm, intended for use in personal computers and other systems requiring thermal monitoring and management. The device can measure the temperature of a microprocessor using a diode-connected NPN or PNP transistor, which may be provided on-chip in the case of the Pentium® II or similar processors, or can be a low-cost discrete device such as the 2N3904.
