3 Description

The LMV7275-Q1 is a single rail-to-rail input low power comparator, characterized at supply voltages of 1.8 V, 2.7 V, and 5 V. It consumes as little as 9-uA supply current per channel while achieving a 800-ns propagation delay.

The LMV7275-Q1 is available in a SC-70 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 LMV7275-Q1 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-Q1, which is useful for level-shifting applications.

The LMV7275-Q1 is built with Texas Instruments' advance submicron silicon-gate BiCMOS process. It has bipolar inputs for improved noise performance, and CMOS outputs for lowest negative output swing.
