GENERAL DESCRIPTION
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 90nm and 65nm CPU diodes) and automatic diode type detection combine to provide a robust solution for complex environmental monitoring applications.
