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.
