EMC1812 - Microchip

EMC1812 Multi-Channel Low-Voltage Remote Diode Sensor

The EMC1812/13/14/15/33 devices are high-accuracy, two-wire (I2C) temperature sensors. The devices monitor up to five temperature channels. Advanced features, such as Resistance Error Correction (REC), Beta Compensation (to support CPU diodes requiring the BJT/Transistor model) and rate of temperature change measurement combine to provide a robust solution .
