    Multiple Channel 1°C Temperature Sensor with
    Beta Compensation
    PRODUCT FEATURES Data Sheet General Description Applications The EMC1412 is a high accuracy, low cost, System
    Management Bus (SMBus) 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 EMC1412 monitors two temperature channels (one
    external and one internal). It provides ±1°C accuracy for
    both external and internal diode temperatures.
    Resistance Error Correction automatically eliminates the
    temperature error caused by series resistance allowing
    greater flexibility in routing thermal diodes. Beta
    Compensation eliminates temperature errors caused by
    low, variable beta transistors common in today's fine
    geometry processors. The automatic beta detection
    feature monitors the external diode/transistor and
    determines the optimum sensor settings for accurate
    temperature measurements regardless of processor
    technology. This frees the user from providing unique
    sensor configurations for each temperature monitoring ...
