LMV7235/LMV7239

45ns, Ultra Low Power, Low Voltage, Rail-to-Rail Input

Comparator with Open-Drain/Push-Pull Output

General Description

Features

The LMV7235/39 are ultra low power, low voltage, 45ns

comparators. They are guaranteed to operate over the full

supply voltage range of 2.7V to 5V. These devices achieve a

45ns propagation delay while consuming only 65µA of sup-

ply current at 5V.

(V_S= 5V, T_A= 25˚C, Typical values unless otherwise speci-

fied)

n Propagation delay

n Low supply current

n Rail-to-Rail input

45ns

65µA

The LMV7235/39 have a greater than rail-to-rail common

mode voltage range. The input common mode voltage range

extends 200mV below ground and 200mV above supply,

allowing both ground and supply sensing.

n Open drain and push-pull output

n Ideal for 2.7V and 5V single supply applications

n Available in space saving packages: 5-pin SOT23-5

and 5-pin SC70-5

The LMV7235 features an open drain output. By connecting

an external resistor, the output of the comparator can be

used as a level shifter.

Applications

n Portable and battery powered systems

n Scanners

The LMV7239 features a push-pull output stage. This feature

allows operation without the need of an external pull-up

resistor.

n Set top boxes

n High speed differential line receiver

n Window comparators

n Zero-crossing detectors

n High speed sampling circuits

The LMV7235/39 are available in the SC70-5 and SOT23-5

packages, which are ideal for systems where small size and

low power is critical.
