LMV7272 Datasheet | National Semiconductor

Description The LMV727X are rail-to-rail input low power parators, which are characterized at supply voltage 1.8V, 2.7V and 5.0V. They consume only 9u A 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 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 5V, regardless of the supply voltage of the LMV7275. The LMV727X are built with National Semiconductor’s advance submicron silicon-gate Bi CMOS process. They all have bipolar inputs for improved noise performance and CMOS outputs for rail-to-rail output swing.
