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.
