3 Description

The LMV7235 and LMV7239 are ultra low power, low

voltage, 75-ns comparators. They are ensured to

operate over the full supply voltage range of 2.7 V to

5.5 V. These devices achieve a 75-ns propagation

delay while consuming only 65 μA of supply current

at 5 V.

The LMV7235 and LMV7239 have a greater than railto-

rail common-mode voltage range. The input

common mode voltage range extends 200 mV below

ground and 200 mV above supply, allowing both

ground and supply sensing.

The LMV7235 features an open drain output. By

connecting an external resistor, the output of the

comparator can be used as a level shifter.

The LMV7239 features a push-pull output stage. This

feature allows operation without the need of an

external pullup resistor.

The LMV7235 and LMV7239 are available in the 5-

pin SC70 and 5-pin SOT-23 packages, which are

ideal for systems where small size and low power is

critical.
