LMV331/ LMV393
GENERAL PURPOSE LOW VOLTAGE COMPARATOR
Description
The LMV331/LMV393 series are low-voltage, (2.7V to 5.5V) single
and dual comparators, which are designed to effectively reduce cost
and space at low-voltage levels.
These devices offer specifications that meet or exceed the familiar
LM331/LM393 devices operating with a lower supply voltage and
consuming a far lower supply current.
The LMV331 is available in 5-Pin SOT353/SOT25 packages that
reduce space on PC boards and portable electronic devices. LMV393
is available in industry standard SOP-8 and MSOP-8 packages.

LMV331/ LMV393
Application Information
Detailed Description
LMV331/LMV393 are low-voltage single/dual general- purpose comparators. They have a single supply operating voltage range from 2.7V to 5.5V;
the common mode input voltage range extends from -0.1V below the negative supply to within 0.8V of the positive supply.
The LMV331/393 series is built using the BiCMOS process with bipolar input and output stages for improved noise performance. It is a cost-
effective solution for portable consumer products where space, low voltage, low power and price are the primary specification in circuit design.
Basic Comparator
A basic comparator circuit is used for converting analog signal to digital output. The LMV331/393 has open-collector output structure, which
required a pull-high resistor to positive supply voltage for the output to switch properly. When the internal output transistor is off, the output voltage
will be pulled up to the external positive voltage.
The output pull- up resistor should be chosen high enough so as to avoid excessive power dissipation, yet low enough to supply enough drive to
switch whatever load circuitry is used on the comparator output. On the LMV331/393 the pull-up resistor should range between 1KΩ to 10KΩ.
Power Supply Bypassing
For better performance, power supply bypass capacitor is necessary. For a single-supply operation system, a minimum of 0.1µF bypass capacitor
should be recommended to place as close as possible between VCC pin and GND.
