DESCRIPTION
The LMV7235/LMV7239/LMV7239Q are ultra low
power, low voltage, 75 nsec comparators. They are
guaranteed to operate over the full supply voltage
range of 2.7V to 5.5V. These devices achieve a 75
nsec propagation delay while consuming only 65µA
of supply current at 5V.
The LMV7235/LMV7239/LMV7239Q 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/LMV7239Q features a push-pull output
stage. This feature allows operation without the need
of an external pull-up resistor.
The LMV7235/LMV7239/LMV7239Q 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.
