internal 10ppm/°C reference minimizes the number of  
supporting components and area required. Selectable  
address and configurable functionality give the LTC2990  
flexibility to be incorporated in various systems needing  
temperature, voltage or current data. The LTC2990 fits  
well in systems needing sub-millivolt voltage resolution,  
1% current measurement and 1°C temperature accuracy  
or any combination of the three.
