LMV7291
Single 1.8V Low Power Comparator with Rail-to-Rail
Input
General Description
The LMV7291 is a rail-to-rail input low power comparator,
characterized at supply voltage 1.8V, 2.7V and 5.0V. It con-
sumes only 9uA supply current per channel while achieving
a 800ns propagation delay.
The LMV7291 is available in SC70 package. With this tiny
package, the PC board area can be significantly reduced. It
is ideal for low voltage, low power and space critical designs.
The LMV7291 features a push-pull output stage which al-
lows operation with minimum power consumption when driv-
ing a load.
The LMV7291 is built with National Semiconductor’s ad-
vance submicron silicon-gate BiCMOS process. It has bipo-
lar inputs for improved noise performance and CMOS out-
puts for rail-to-rail output swing.
