LMV7251/LMV7255

1.8V Low Voltage Comparator with Rail-to-Rail Input

General Description

Features

The LMV7251/LMV7255 are rail-to-rail input low voltage

comparators, which can operate at supply voltage range of

1.8V to 5.0V. The LMV7251/LMV7255 are available in space

saving SC-70 or SOT23-5 packages. These comparators

are ideal for low voltage and space critical designs.

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

n Single or Dual Supplies

n Low supply voltage

1.8V to 5.0V

n Ultra low supply current

n Low input bias current

n Low input offset current

n Low input offset voltage

n Response time

11µA

14nA

200pA

The LMV7251 features a push-pull output stage. This feature

allows operation with minimum power consumption when

driving a load.

+/−0.3mV

670ns (20mV overdrive)

0.1V beyond rails

The LMV7255 features an open drain output. This allows the

connection of an external resistor at the output. The output of

the comparator can be used as a level shifter.

n Input common mode voltage

Applications

n Mobile communications

n Laptops and PDA’s

n Battery powered electronics

n General purpose low voltage applications

The IC’s are built with National Semiconductor’s advance

Submicron

Silicon-Gate

BiCMOS

process.

The

LMV7251/LMV7255 have bipolar inputs for improved noise

performance and CMOS outputs for better rail-to-rail output

performance.
