Single 1.8V Low Power Comparators with Rail-to-Rail Input - LMV7275

LMV7275 (ACTIVE)

Single 1.8V Low Power Comparators with Rail-to-Rail Input

Recommended alternative parts

  • LPV7215  -  Lower Supply Current Consumption (600nA), Output (Push Pull)

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 SOT-23 packages. The LMV7272 (dual) is available in DSBGA 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 5.5V, regardless of the supply voltage of the LMV7275.

The LMV727X 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.
