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.
