GENERAL DESCRIPTION  
The ADCMP670 combine two low power, low voltage  
comparators with a 400mV reference in the 6-lead TSOT  
package. Operating within a supply range of 1.7V to 5.5V, the  
devices only draw 6.5µA typical, making them ideal for low  
voltage system monitoring and portable applications.  
Hysteresis is included in the comparators to insure stable  
output operation. Each comparator has only one input available  
externally, the other inputs are connected internally to the  
reference. The comparator outputs are open collector and the  
output load can be referred to any voltage up to supply voltage.  
The output stage sinking capability guaranteed greater than  
5mA over temperature.  
The ADCMP670 has one inverting input and one non-  
inverting input, making it suitable for use as a window  
comparator. Available in commercial, industrial and  
automotive temperature ranges.
