Datasheet  
PRODUCT FEATURES  
General Description  
Features  
„
Pin Compatible with ADM1032, MAX6649, and LM99  
External Temperature Monitors  
The EMC1072 is a high accuracy, low cost, System  
Management Bus (SMBus) temperature sensor with pin  
selectable SMBus address.  
„
±0.25°C typ accuracy (20°C < TDIODE < 110°C)  
0.125°C resolution  
Supports 2N3904 and AMD diodes  
The device provides ±1° accuracy (max) for external  
diode temperatures and ±2°C accuracy (max) for the  
internal diode temperature. The EMC1072 monitors two  
temperature channels (one external and one internal).
