产品信息
The EMC1187 is a high accuracy, low cost, I2C/SMBus three channel temperature sensor with a hardware defined shutdown. Advanced features such as Resistance Error Correction (REC), Beta Compensation (to support CPU diodes requiring the BJT/transistor model) and automatic diode type detection combine to provide a robust solution for complex environmental monitoring applications.
The EMC1187 monitors three temperature channels (two external and one internal). It provides ±1°C accuracy for both external and internal diode temperatures. Frequency hopping and analog filtering ensure remote diode traces can be as far as 8 inches without degrading the signal.
