    EMC1403/EMC1404 1°C Temperature Sensor with Beta Compensation PRODUCT FEATURES Data Sheet General Description Applications The EMC1403 and EMC1404 are high accuracy, low
    cost, System Management Bus (SMBus) temperature
    sensors. Advanced features such as Resistance Error
    Correction (REC), Beta Compensation (to support CPU
    diodes requiring the BJT/transistor model including
    45nm, 65nm and 90nm processors) and automatic
    diode type detection combine to provide a robust
    solution for complex environmental monitoring
    applications.  Each device provides ±1° accuracy for external diode
    temperatures and ±2°C accuracy for the internal diode
    temperature. The EMC1403 monitors three temperature
    channels (two external and one internal). The EMC1404
    monitors four temperature channels (three external and
    one internal).   Internal Temperature Monitor 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 each external diode/transistor and
    determines the optimum sensor settings for accurate
    temperature measurements regardless of processor
    technology. This frees the user from providing unique ...
