ADT7482传感器变送器的温度传感器-模拟数字输出规格书PDF中文资料

ADT7482属于传感器变送器的温度传感器-模拟数字输出。由安森美半导体公司制造生产的ADT7482温度传感器 - 模拟和数字输出模拟和数字输出温度传感器可用于测量环境热能量。特征包括传感器类型、本地感测温度、远程感测温度、输出类型、电源电压和分辨率。传感器类型为模拟本地/远程/红外、模拟数字、本地/远程、数字本地/远程/红外或内部，感应温度范围为 -55°C 至 200°C。

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.

One feature of the ADT7482 is series resistance cancellation where up to 1.5 kΩ (typical) of resistance in series with each of the temperature monitoring diodes can be automatically cancelled from the temperature result, allowing noise filtering. The temperature of the remote thermal diodes and ambient temperature can be measured accurate to ±1°C. The temperature measurement range, which defaults to 0°C to 127°C, can be switched to a wider measurement range of from −55°C to +150°C.
