FEATURES  
DESCRIPTION  
Guaranteed Maximum 0.5mV Input Offset Voltage  
Input Protection Diodes  
Operates From Single 5V Supply  
25mA Drive Capability  
80ns Response Time  
The LT119A is an improved version of the LM119 dual  
comparator. It features lower input offset voltage and  
offset current, higher voltage gain, guaranteed common  
mode rejection, and input protection diodes.  
The LT119A is capable of operation over a supply range  
from5Vto±15Vandcandrive25mAloadsfromeachopen
