LMV7291

Single 1.8V Low Power Comparator with Rail-to-Rail

Input

General Description

Features

The LMV7291 is a rail-to-rail input low power comparator,

characterized at supply voltage 1.8V, 2.7V and 5.0V. It con-

sumes only 9uA supply current per channel while achieving

a 800ns propagation delay.

(V_S= 1.8V, T_A= 25˚C, Typical values unless specified).

n Single Supply

n Ultra low supply current

n Low input bias current

n Low input offset current

n Low guaranteed V_OS

n Propagation delay

9µA per channel

10nA

200pA

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.

880ns (20mV overdrive)

The LMV7291 features a push-pull output stage which al-

lows operation with minimum power consumption when driv-

ing a load.

n Input common mode voltage range

0.1V beyond rails

Applications

The LMV7291 is built with National Semiconductor’s ad-

vance submicron silicon-gate BiCMOS process. It has bipo-

lar inputs for improved noise performance and CMOS out-

puts for rail-to-rail output swing.

n Mobile communications

n Laptops and PDA’s

n Battery powered electronics

n General purpose low voltage applications
