1. On-chip temperature sensor allows an accurate  
measurement of the ambient temperature. The measurable  
temperature range is −55°C to +125°C.  
2. Supply voltage is 3.0 V to 5.5 V.  
3. Space-saving, 8-lead MSOP and 8-lead SOIC.  
4. Temperature accuracy is 1°C maꢀimum.  
5. Temperature resolution is 0.0625°C.  
Overtemperature indicator  
Shutdown mode for low power consumption  
Power consumption 79 μW typically at 3.3 V  
Small, low cost 8-pin MSOP in Pb-Sn and Pb-free packages  
Standard 8-pin SOIC Pb-free package  
6. Shutdown mode reduces the current consumption to  
3 μA typical.  
7. Connect up to eight ADT75s to a single SMBus/I2C bus.
