ADM1032* General Description
The ADM1032 is a dual-channel digital thermometer and under/over temperature alarm, intended for use in personal computers and thermal management systems. The higher 1°C accuracy offered allows systems designers to safely reduce temperature guardbanding and increase system performance. The device can measure the temperature of a microprocessor using a diode-connected NPN or PNP transistor, which may be provided on-chip or can be a low-cost discrete device such as the 2N3906. A novel measurement technique cancels out the absolute value of the transistor's base emitter voltage, so that no calibration is required. The second measurement channel measures the output of an on-chip temperature sensor, to monitor the temperature of the device and its environment.
