LMV7271/LMV7275/LMV7272

Single & Dual, 1.8V Low Power Comparators with Rail-to-

Rail Input

General Description

Features

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.

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

Single or Dual Supplies

■

Ultra low supply current

Low input bias current

Low input offset current

Low guaranteed V_OS

Propagation delay

9µA per channel

■

10nA

200pA

4mV

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.

880ns (20mV overdrive)

Input common mode voltage range

LMV7272 is available in micro SMD package

0.1V beyond rails

The LMV7271/LMV7272 both feature a push-pull output

stage which allows operation with minimum power consump-

tion 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.

Applications

Mobile communications

■

Laptops and PDA's

Battery powered electronics

General purpose low voltage applications

The LMV727X are built with National Semiconductor's ad-

vance submicron silicon-gate BiCMOS process. They all

have bipolar inputs for improved noise performance and

CMOS outputs for rail-to-rail output swing.
