3 Description

The LMV727x devices are rail-to-rail input low power

comparators, characterized at supply voltages 1.8 V,

2.7 V, and 5 V. They consume as little as 9-uA supply

current per channel while achieving a 800-ns

propagation delay.

The LMV7271 and LMV7275 (single) are available in

SC70 and SOT-23 packages. The LMV7272 (dual) is

available in the DSBGA package. With these tiny

packages, the PCB area can be significantly reduced. They are ideal for low voltage, low power, and space-

critical designs.

The LMV7271 and LMV7272 both feature a push-pull

output stage which allows operation with minimum

power consumption 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 5.5 V, regardless of the supply voltage of the LMV7275,

which is useful for level-shifting applications.

The LMV727x devices are built with Texas

Instruments' advance submicron silicon-gate BiCMOS

process. They all have bipolar inputs for improved

noise performance, and CMOS outputs for rail-to-rail

output swing.
