Device Overview

Summary

The EMC1182 is a high accuracy, low cost, I2C/SMBus dual channel temperature sensor. 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 EMC1182 monitors two temperature channels (one 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.

EMC1182 Evaluation Board
EMC1182 Evaluation Board ( ADM00516 )

The EMC1182 Temp Sensor Evaluation Board provides the means to demonstrate all of the EMC1182 features, and allows to view and modify registers. LEDs indicating status information and test points are included to enable system voltages monitoring, using a voltmeter or an oscilloscope. The board requires only one universal serial bus (USB) connection to power the board. The USB-to-SMBus bridge...
