EMC1046/EMC1047 1??C Multiple Temperature Sensor with Beta Compensation and Hot

EMC1046/EMC1047
1°C Multiple Temperature
Sensor with Beta
Compensation and
Hottest of Thermal Zones
PRODUCT FEATURES
Data Brief
General Description
Features
The EMC1046/EMC1047 are high accuracy, low cost,
System Management Bus (SMBus) temperature
sensors. Advanced features such as Resistance Error
Correction (REC), Beta Compensation (to CPU diodes
requiring the BJT or transistor model) 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 EMC1046/EMC1047 monitors up to
seven temperature channels (up to six external and one
internal).
