FEATURES  
DESCRIPTION  
The LTC®1440/LTC1441/LTC1442 are ultralow power  
single and dual comparators with built-in references. The  
comparators feature less than 3.7µA supply current over  
temperature (LTC1440), a 1.182V ±1% reference, pro-  
grammablehysteresis(LTC1440/LTC1442)andTTL/CMOS  
outputsthatsinkandsourcecurrent. Thereferenceoutput  
can drive a bypass capacitor of up to 0.01µF without  
oscillation.  
■
Ultralow Quiescent Current: 2.1µA Typ (LTC1440)  
■
Wide Supply Range:  
Single: 2V to 11V  
Dual: ±1V to ±5.5V  
■
Input Voltage Range Includes the Negative Supply

Reference Output Drives 0.01µF Capacitor  
Adjustable Hysteresis (LTC1440/LTC1442)  
TTL/CMOS Compatible Outputs  
12µs Propagation Delay with 10mV Overdrive  
No Crowbar Current  
40mA Continuous Source Current  
Pin Compatible Upgrades for MAX921/922/923  
The comparators operate from a single 2V to 11V supply  
or a dual ±1V to ±5.5V supply (LTC1440). Comparator  
hysteresis is easily programmed by using two resistors  
andtheHYSTpin(LTC1440/LTC1442).Eachcomparator’s  
input operates from the negative supply to within 1.3V of  
the positive supply. The comparator output stage can  
continuously source up to 40mA. By eliminating the  
cross-conductingcurrentthatnormallyhappenswhenthe  
comparatorchangeslogicstates,thepowersupplyglitches  
are eliminated.
