ADT7461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

ADT7461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ADT7461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 ADT7461 is a dual-channel digital thermometer and under/over temperature alarm intended for use in PCs and thermal management systems. It is pin- and register-compatible with the ADM1032. The ADT7461 has three additional features: series resistance cancellation (where up to 3 kΩ(typical) of resistance in series with the temperature monitoring diode may be automatically cancelled from the temperature
