    EMC1402 1°C Temperature Sensor with
    Beta Compensation PRODUCT FEATURES Datasheet General Description Applications The EMC1402 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 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 EMC1402 monitors two temperature
    channels (one external and one internal). „ 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
    application. These advanced features plus ±1°C ...
