Product specification  
Low power dual voltage comparator  
AU2903  
DESCRIPTION  
PIN CONFIGURATION  
The AU2903 consists of two independent precision voltage  
comparators with an offset voltage specification as low as 2.0mV  
max. for two comparators which were designed specifically to  
operate from a single power supply over a wide range of voltages.  
Operation from split power supplies is also possible and the low  
power supply current drain is independent of the magnitude of the  
power supply voltage. These comparators also have a unique  
characteristic in that the input common-mode voltage range includes  
ground, even though operated from a single power supply voltage.
