ADT7483AARQZ-R7

双通道温度传感器和超温报警 Dual Channel Temperature Sensor and Over Temperature Alarm

The ADT7483A is a three-channel digital thermometer and under/over temperature alarm, intended for use in PCs and thermal management systems. It can measure the temperature in two remote locations, for example, the remote thermal diode in a CPU or GPU, or a discrete diode connected transistor. It can also measure its own ambient temperature.
