±1°C 温度传感器，带串联电阻抵消
Obsolete
概览
NCT1008 是一款双沟道数字温度传感器，用于更高热密度应用。 NCT1008 具有串联电阻抑制功能，可从温度结果中自动消除温度监控二极管高达 1.5 kΩ 的串联电阻，从而滤除噪声。NCT1008 有一个可配置的 ALERT 输出，以及可切换的宽广温度测量范围。NCT1008 的远程热二极管温度测量准确度为 ±1°C，环境温度测量准确度为 ±3°C。温度测量范围默认为 0°C 至 +127°C，与 ADM1032 兼容，但它可以切换为更宽的测量范围 -64°C 至 +191°C。NCT1008 通过 2 线串行接口进行通信，符合系统管理总线 (SMBus/I2C) 标准。NCT1008 的默认 SMBus/I2C 地址是 0x4C。NCT1008D 的 SMBus/I2C 地址是 0x4D。如同一 SMBus/I2C 上使用了一个以上的 NCT1008，地址会非常有用。当片上或远程温度超出范围时，/ALERT 输出会发出信号。THERM 输出是一个比较器输出，可以控制冷却风扇的开关。如果需要，可以将 ALERT 输出重新配置为次级 THERM 输出。
