LM86 具有双线接口的 ±0.75°C 精确、远程二极管和本地数字温度传感器
The LM86 is an 11-bit digital temperature sensor with a 2-wire System Management Bus (SMBus) serial interface. The LM86 accurately measures its own temperature as well as the temperature of an external device, such as processor thermal diode or diode connected transistor such as the 2N3904. The temperature of any ASIC can be accurately determined using the LM86 as long as a dedicated diode (semiconductor junction) is available on the target die. The LM86 remote sensor accuracy of ±0.75°C is factory trimmed for the 1.008 typical non-ideality factor of the mobile Pentium™ III thermal diode. The LM86 has an Offset register to allow measuring other diodes without requiring continuous software management.
