Features (VS = 1.8V, TA = 25°C, Typical values unless specified). Single Supply 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 Description The LMV7291 is a rail-to-rail input low power comparator, characterized at supply voltage 1.8V, 2.7V and 5.0V. It consumes only 9uA supply current per channel while achieving a 800ns propagation delay. The LMV7291 is available in SC70 package. With this tiny package, the PC board area can be significantly reduced. It is ideal for low voltage, low power and space critical designs. The LMV7291 features a push-pull output stage which allows operation with minimum power consumption when driving a load. The LMV7291 is built with National Semiconductor's advance submicron silicon-gate BiCMOS process. It has bipolar inputs for improved noise performance and CMOS outputs for rail-to-rail output swing. Applications Mobile communications Laptops and PDA's Battery powered electronics General purpose low voltage applications

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LMV7291MG	CS080	0	30715	0	0	2900500	2	823024794
LMV7291MGX	CS080	0	30715	0	0	2900500	2	823024794

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.
