FEATURES  
DESCRIPTION  
TheLTC®1841/LTC1842/LTC1843areultralowpowerdual  
comparators with built-in reference (LTC1842/LTC1843).  
The comparators feature less than 5.7µA supply current  
over temperature, a 1.182V ±1% reference, program-  
mable hysteresis and open-drain outputs that sink cur-  
rent. The reference output can drive a bypass capacitor of  
up to 0.01µF without oscillation.  
Ultralow Quiescent Current: 3.5µA Typ  
Open-Drain Outputs Typically Sink  
Greater Than 20mA  
Wide Supply Range: (LTC1841)  
Single: 2V to 11V  
Dual: ±1V to ±5.5V  
Input Voltage Range Includes the Negative Supply  
Reference Output Drives 0.01  
µF Capacitor  
The LTC1841 operates from a single 2V to 11V supply or  
a dual ±1V to ±5.5V supply. The LTC1842/LTC1843  
operate from a single 2.5V to 11V supply or a dual ±1.25V  
to ±5.5V supply. The LTC1842/LTC1843 hysteresis is  
easily programmed by using two resistors and the HYST  
pin. The comparators’ input operates from the negative  
supply to within 1.3V of the positive supply. The compara-  
tors’ output stage can typically sink greater than 20mA. By  
eliminating the cross-conduction current that normally  
happenswhenthecomparatorschangelogicstates,power  
supply glitches are eliminated.  
Adjustable Hysteresis  
12µs Propagation Delay with 10mV Overdrive  
No Current Spike When Switching
