Features (VS = 1.8V, TA = 25°C, Typical values unless specified). Single or Dual Supplies Ultra low supply current 9µA per channel Low input bias current 10nA Low input offset current 200pA Low guaranteed VOS 4mV Propagation delay 880ns (20mV overdrive) Input common mode voltage range 0.1V beyond rails LMV7272 is available in micro SMD package 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 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 5.5V, regardless of the supply voltage of the LMV7275. The LMV727X are built with National Semiconductor's advance submicron silicon-gate BiCMOS process. They all have bipolar inputs for improved noise performance and CMOS outputs for rail-to-rail output swing.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
