LMV7251/LMV7255  
1.8V Low Voltage Comparator with Rail-to-Rail Input  
General Description  
Features  
The LMV7251/LMV7255 are rail-to-rail input low voltage  
comparators, which can operate at supply voltage range of  
1.8V to 5.0V. The LMV7251/LMV7255 are available in space  
saving SC-70 or SOT23-5 packages. These comparators  
are ideal for low voltage and space critical designs.  
(VS = 1.8V, TA = 25˚C, Typical values unless specified).  
n Single or Dual Supplies  
n Low supply voltage  
1.8V to 5.0V  
n Ultra low supply current  
n Low input bias current  
n Low input offset current  
n Low input offset voltage  
n Response time  
11µA  
14nA  
200pA  
The LMV7251 features a push-pull output stage. This feature  
allows operation with minimum power consumption when  
driving a load.  
+/−0.3mV  
670ns (20mV overdrive)  
0.1V beyond rails  
The LMV7255 features an open drain output. This allows the  
connection of an external resistor at the output. The output of  
the comparator can be used as a level shifter.  
n Input common mode voltage  
Applications  
n Mobile communications  
n Laptops and PDA’s  
n Battery powered electronics  
n General purpose low voltage applications  
The IC’s are built with National Semiconductor’s advance  
Submicron  
Silicon-Gate  
BiCMOS  
process.  
The  
LMV7251/LMV7255 have bipolar inputs for improved noise  
performance and CMOS outputs for better rail-to-rail output  
performance.
