ADT7482 Description
ADT7482 Dual Channel Temperature Sensor and Overtemperature Alarm The ADT7482 is a three-channel digital thermometer and under/overtemperature alarm for PCs and thermal management systems. It can measure the temperature in two remote locations, such as in the remote thermal diode in a CPU or GPU, or using a discrete diode connected transistor. This device also measures its own ambient temperature.
