LMV7235/LMV7239
45ns, Ultra Low Power, Low Voltage, Rail-to-Rail Input
Comparator with Open-Drain/Push-Pull Output
General Description
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.
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.
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 pull-up
resistor.
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.
