LMV7271/LMV7275/LMV7272
Single & Dual, 1.8V Low Power Comparators with
Rail-to-Rail Input
General Description
The LMV727X are rail-to-rail input low power comparators,
which are characterized at supply voltage 1.8V, 2.7V and
5.0V. They consume only 9uA supply current per channel
while achieving a 800ns propagation delay.
The LMV7271/LMV7275 (single) are available in SC70 and
SOT23 packages. The LMV7272 (dual) is available in micro
SMD package. With these tiny packages, the PC board area
can be significantly reduced. They are ideal for low voltage,
low power and space critical designs.
The LMV7271/LMV7272 both feature a push-pull output
stage which allows operation with minimum power consump-
tion when driving a load. The LMV7275 features an open
drain output stage that allows for wired-OR configurations.
The open drain output also offers the advantage of allowing
the output to be pulled to any voltage up to 5V, regardless of
the supply voltage of the LMV7275.
The LMV727X are built with National Semiconductor’s ad-
vance submicron silicon-gate BiCMOS process. They all
have bipolar inputs for improved noise performance and
CMOS outputs for rail-to-rail output swing.
