The ADM1032 is a dual-channel digital thermometer and under/overtemperature alarm intended for use in PCs and thermal management systems.The device can measure the temperature of a remote thermal diode, which can be located on the processor die or can be a discrete device (2N3904/06), accurate to 1°C.A novel measurement technique cancels out the absolute value of the transistor's base emitter voltage so that no calibration is required.The ADM1032 also measures its ambient temperature.
