•
(VS = 1.8V, TA = 25°C, Typical
Values unless Specified)
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.

Single Supply
Ultra Low Supply Current 9µA per Channel
Low Input Bias Current 10nA
Low Input Offset Current 200pA
Low ensured VOS 4mV
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.
Propagation Delay 880ns (20mV Overdrive)
The LMV7291 features a push-pull output stage
which allows operation with minimum power
consumption when driving a load.
Input Common Mode Voltage Range 0.1V
beyond Rails
The LMV7291 is built with Texas Instruments'
advance submicron silicon-gate BiCMOS process. It
has bipolar inputs for improved noise performance
and CMOS outputs for rail-to-rail output swing.
