Comparators with Reference  
FeaTures  
DescripTion  
TheLTC®1443/LTC1444/LTC1445areultralowpowerquad  
comparators with a built-in reference. The comparators  
feature less than 8.5µA supply current over temperature,  
an internal reference (1.182V 1ꢀ for LTC1443 or 1.221V  
1ꢀ for LTC1444/LTC1445), programmable hysteresis  
(LTC1444/LTC1445) and TTL/CMOS output (LTC1443/  
LTC1445) that sinks and sources current (open-drain  
output for LTC1444). The reference output can drive a  
bypass capacitor of up to 0.01µF without oscillation.

The comparators operate from a single 2V to 11V supply  
or a dual 1V to 5.5V supply (LTC1443). Comparator

operates from the negative supply to within 1.3V of the  
positivesupply.TheLTC1443/LTC1445comparatoroutput  
stage can continuously source up to 40mA. By eliminat-  
ing the cross-conducting current that normally happens  
when the comparator changes logic states, power supply  
glitches are eliminated.
