Figure 5.3 Block Diagram of Temperature Monitoring Circuit  
Figure 5.3 shows a block diagram of the temperature measurement circuit. As shown, the EMC2101  
incorporates a delta-sigma analog to digital converter that integrates the temperature diode voltage  
from multiple bias currents.  
The external temperature diodes can be connected as shown in Figure 5.4.

Temperature Measurement Results and Data  
The results of the internal and external temperature measurements are stored in the internal and  
external temperature registers respectively. These are then compared with the values stored in the  
High Limit Registers. The internal temperature measurements are stored in 8-bit format while the  
external temperature measurements are stored in 11-bit format.
