The LMV393-N and LMV339-N are low-voltage (2.7 to 5 V) versions of the dual and quad comparators, LM393/339, which are specified at 5 to 30 V. The LMV331-N is the single version, which is available in space-saving, 5-pin SC70 and 5-pin SOT23 packages. The 5-pin SC70 is approximately half the size of the 5-pin SOT23.
The LMV393-N is available in 8-pin SOIC and VSSOP packages. The LMV339-N is available in 14-pin SOIC and TSSOP packages.
The LMV331-N/393-N/339-N is the most cost-effective solution where space, low voltage, low power, and price are the primary specification in circuit design for portable consumer products. They offer specifications that meet or exceed the familiar LM393/339 at a fraction of the supply current.
The chips are built with TI's advanced Submicron Silicon-Gate BiCMOS process. The LMV331-N/393-N/339-N have bipolar input and output stages for improved noise performance.

The LMV331-N/393-N/339-N comparators features a supply voltage range of 2.7 V to 5 V with a low supply current of 55 μA/channel with propagation delays as low as 200ns. They are avaialble in small, space-saving packages, which makes these comparators versatile for use in a wide range of applications, from portable to industrial. The open collector output configuration allows the device to be used in wired-OR configurations, such as a window comparators.
The output of the LMV331-N/393-N/339-N series is the uncommitted collector of a grounded-emitter NPN output transistor, which requires a pull-up resistor to a positive supply voltage for the output to switch properly. Many collectors can be tied together to provide an output OR’ing function. An output pull-up resistor can be connected to any available power supply voltage within the permitted V+ supply voltage range. 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-N/393-N/339-N the pull-up resistor should range between 1 k to 10 kΩ.
The LMV331-N/393-N/339-N has a typical input common mode voltage range of −0.1V below the ground to 0.8V below Vcc.
A basic comparator circuit is used for converting analog signals to a digital output.
The output is HIGH when the voltage on the non-inverting (+IN) input is greater than the inverting (-IN) input.
The output is LOW when the voltage on the non-inverting (+IN) input is less than the inverting (-IN) input.
The inverting input (-IN) is also commonly referred to as the "reference" or "VREF" input.
